Nanotechnology/Biosensors

=Biosensors= Biological sensor functionalisation, receptors and signals
 * Assays for measuring the biochemical properties, such as immunesystem responses, specific proteins etc.
 * DNA binding protein
 * Functional group
 * Receptor biochemistry
 * Neuron
 * The Biotin -  Streptavidin binding is the strongest biochemical bond and often used when you need to demonstrate a sensor or bind different biomolecules together.
 * Biofouling - by using certain polymers such as PEG or PLL-PEG, cell adhesion to surface can be drastically reduced.

DNA Biosensors
In the future, DNA will find use as a versatile material from which scientists can craft biosensors. DNA biosensors can theoretically be used for medical diagnostics, forensic science, agriculture, or even environmental clean-up efforts. No external monitoring is needed for DNA-based sensing devices. This is a significant advantage. DNA biosensors are complicated mini-machines—consisting of sensing elements, micro lasers, and a signal generator. At the heart of DNA biosensor function is the fact that two strands of DNA stick to each other by virtue of chemical attractive forces. On such a sensor, only an exact fit—that is, two strands that match up at every nucleotide position—gives rise to a fluorescent signal (a glow) that is then transmitted to a signal generator.
