Generally biochips are made for making our life easier. For this reason the ultimate biochip consists a complete LOC to perform an inclusive analysis of biological, chemical, and physical parameters; and also includes a therapeutic BioMEMS (Micro-Electro-Mechanical System), for instance a drug delivery or an electro-stimulation sub-system. There are lots of practical problems that need to be solved before this type of biochip becomes reality. For examples the regeneration of biochemical sensing surfaces, bio-fouling resistance, robustness in the chemically aggressive environment of the body of animals and human beings, long-term power-supply using biofuel harvesting or inductive coupling [8].
The analytes of optical biochips depend on the actual biochemical function of the type of molecule. Different classes of analytes describing below:
DNA chips contain a large number (up to one million) of different single-stranded DNA fragments that analysis the genetic information of a cell. These biochips are halted on the substrate surface in discrete spots. To increase sensitivity each spot contains several millions of identical oligonucleotides. The sample which needs to be tested usually labeled with a fluorescent dye and it contains single-stranded genetic chains (DNA fragments, mRNA, or cDNA). The genetic chains become blind to the spot on the substrate when they match with the immobilized oligonucleotides. The biochip is then illuminated with a suitable wavelength, so that the fluorescence light pattern of the different spots allows the determination of the type and concentration of target genetic chains in the sample [2].
The identification of proteins (proteomics) is more important than genomics when the genetic information discover...

Direct write laser micromachining is illustrated in figure 3a. In direct write laser micromachining process, the laser beam is focused to a small spot using a lens and either the beam or the sample (or both) are moved around to produce the desired pattern. Generally this process uses a laser with a Gaussian beam profile. Because of the good beam quality and a low M2 factor, it allows the beam to be focused to a small spot using simple optical components and give the beam fluence at focus that is above the ablation threshold of the workpiece material.
By controlling the beam movement over the surface of the workpiece, 2D patterns can be machined. Again overlaying machining runs, 3D structures can also produce. Machining depth control during workpiece movement is achieved by synchronizing laser pulse or power output with workpiece stage position.
They now are very useful in allowing amputees to lead a more normal life. This paper will outline the advanced technology of bionic limbs. These bionic products combine artificial intelligence with human philosophy to create a more human-like way to restore the function of a lost limb. These bionic limbs take the pressure off amputees by sensing how their lost limb should move and adapts to movement of the amputee. The bionic product automatically controls itself without the amputee having to think about how to move it. The purpose of this paper is to inform about bionic products. It will further explain how they operate, along with their efficacy in prosthetics. Innovative bionic technology continuously increases the quality of life for amputees. That innovative technology will be explored through this paper, along with their specific functions and operations. The new products like the Power Knee, the Rheo Knee, the Propio Foot, and Symbiotic leg allow more mobility and individualistic movement for the amputee. Each was developed and tested to be efficient in the prosthetic world. I will explore case studies of people who have these products. I will explore the struggles and adaptions they had to make with the use of this technology.
Using PCR and Gel Electrophoresis to Determine Genotype. In certain situations, it is necessary to identify DNA retrieved from a sample. When there is a small sample in need of identification, Polymerase Chain Reactions are used to multiply the DNA. in the sample in many identical samples.
The given DNA ladder sample and each individual ligation samples were run on 40ml of 0.8% agarose in 1x TAE buffer for approximately sixty minutes at 110V. The appropriate volume of 6x GelRed track dye was used after it was diluted to a final concentration of 1x and incubated for thirty minutes. Finally, the gel was illuminated under UV light and analyzed.
The use of bioethics to alter one’s physical and mental happiness is portrayed as deceitful to many. This critical analysis evaluates an essay that pledges justification for self-improvement as morally right. The essay, “Bioengineering and Self-Improvement,” was written by Arthur Caplan, professor of bioethics and the University of Pennsylvania and director of Center for Bioethics. As presented in the essay, the author is supports using technology in improving one’s vigor and appearance. In fact, he declares that bioengineering improves one’s self through boosted confidence and self-respect. The author furnishes strong points and his essay is convincing of positive outcomes provided with biotechnology. The author has effectively proven this
Proteogenomics is a kind of science field that includes proteomics and genomics. Proteomic consists of protein sequence information and genomic consists of genome sequence information. It is used to annotate whole genome and protein coding genes. Proteomic data provides genome analysis by showing genome annotation and using of peptides that is gained from expressed proteins and it can be used to correct coding regions.Identities of protein coding regions in terms of function and sequence is more important than nucleotide sequences because protein coding genes have more function in a cell than other nucleotide sequences. Genome annotation process includes all experimental and computational stages.These stages can be identification of a gene ,function and structure of a gene and coding region locations.To carry out these processes, ab initio gene prediction methods can be used to predict exon and splice sites. Annotation of protein coding genes is very time consuming process ,therefore gene prediction methods are used for genome annotations. Some web site programs provides these genome annotations such as NCBI and Ensembl. These tools shows sequenced genomes and gives more accurate gene annotations. However, these tools may not explain the presence of a protein. Main idea of proteogenomic methods is to identify peptides in samples by using these tools and also with the help of mass spectrometry.Mass spectrometry searches translation of genome sequences rather than protein database searching. This method also annotate protein protein interactions.MS/MS data searching against translation of genome can determine and identify peptide sequences.Thus genome data can be understood by using genomic and transcriptomic information with this proteogenomic methods and tools. Many of proteomic information can be achieved by gene prediction algorithms, cDNA sequences and comparative genomics. Large proteomic datasets can be gained by peptide mass spectrophotometry for proteogenomics because it uses proteomic data to annotate genome. If there is genome sequence data for an organism or closely related genomes are present,proteogenomic tools can be used. Gained proteogenomic data provides comparing of these data between many related species and shows homology relationships among many species proteins to make annotations with high accuracy.From these studies, proteogenomic data demonstrates frame shifts regions, gene start sites and exon and intron boundaries , alternative splicing sites and its detection , proteolytic sites that is found in proteins, prediction of genes and post translational modification sites for protein.
This tool has a thin metal sheet or ribbon attached to the handle. The ribbon carves into the material.
Optogenetics is a new field of study that’s based upon “the integration of optics and genetics to achieve gain or loss-of-function of well-defined events within specific cells in living tissue.”(Davidson et al. 9) Scientists have now been able to genetically modify virus’ that express their genes only within specific tissues in the body. Once these viruses are inserted into the cell, specific molecules activate the transcription of cell receptors called opsins. Opsins are membrane-bound ion pumps or channels that are sensitive to specific wavelenths of light. They are typically categorized into three groups: Halorhodopsins are chloride pumps that are used to hyperpolarize, or inhibit, the cell membrane; bacteriorhodopsi...
While the idea of human tracking has its share of benefits, there certainly are numerous pitfalls that also exist. While the ability to identify someone with an ID tag may have practical uses, the security and privacy issues could seem potentially alarming to some. Not only that, a closer look may show that the technology doesn’t necessarily offer very many advantages when considering the costs of nation-wide adoption of the technology. This paper will try to investigate into these issues, whilst attempt to come up with some solutions.
Silicon surface micromachining uses the same equipment and processes as the electronics semiconductor industry. There are three basic building blocks in this technology, which are the ability to deposit thin films of material on a substrate, to apply a patterned mask on top of the films by photolithographic imaging, and to etch the films selectively to the mask. A MEMS process is usually a structured sequence of these operations to form actual devices.
By using Messenger RNA- mRNA molecules carrying the code for insulin are common in the cytoplasm of insulin. Or using DNA probes to find the gene required-A probe is a short single strand of DNA carrying the known genetic code we are looking for. So the location of the DNA probe is known, it is labelled with a radioactive fluorescent marker. The aim is for the probe to attach to its complementary base sequence within DNA extracted from human cells.
The scientific and medical progress of DNA as been emense, from involving the identification of our genes that trigger major diseases or the creation and manufacture of drugs to treat these diseases. DNA has many significant uses to society, health and culture of today. One important area of DNA research is that used for genetic and medical research. Our abi...

The phrase “Nobody is perfect” is appropriately accurate since there are many people who are born without arms, legs, or eventually develop organ failure. Bioengineering helps the people living without or damaged tissues and organs to live a better and comfortable life. Bioengineering will help advance and improve the health of humans by applying biology in engineering. Imagine a world without sick people, or people with deformity. This may be hard to imagine, but with the remarkable inventions and solutions developed and produced by bioengineers, this scenario we can currently only imagine in our heads will hopefully eventually become an ordinary norm. It is crucial to help people who were born with a body that restricts them from doing something everyone else can. They deserve to be able to move and be able to do tasks like every other human being.
According to Jennifer A. Wood, Milling is a process in which materials are reduced from a larger size to a smaller size. In the case of pulses there are various processes that can be defined in following way:
