4/25/2023 0 Comments Prima wagner epg 2008 manualDNA biochips may be classified according to the two types of nucleic acid probes affixed to the chip's surface and by the density of such probes presented to a sample. These are nucleic acid (DNA, RNA, and PNA-based types) and protein biochips. In recent times, three main types of biochips have become very important for diagnostic and prognostic purposes. These biochips automate repetitive laboratory tasks by replacing standard equipment with miniaturized microfluidic assays thereby providing very sensitive detection methods ( 2). ![]() Biochips are highly versatile devices that may be used for clinical diagnostics and prognostics, patient stratification in drug development, disease management, and forensic applications, amongst others. Biochips are similar to but may be distinguished over biosensors by the density of functional recognition sites, generally 10 2–10 4. Biochips, as the contraction implies, incorporate biologically derived recognition entities with the additive and subtractive techniques of microlithography in the production of useful analytical devices ( 1).
