Portable biosensors on the base of DNA biosensing units for application in medicine and biotechnologies

The developments of biosensor analytical systems based on double-stranded DNA nanoconstructions as biosensing units and a portable dichrometer are presented. Such systems can be used for high sensitive detection of different biologically active and toxic compounds in liquids. The properties of particles of DNA nanoconstructions and different dichrometer constructions are described, mainly, from the point of view using such biosensors in medicine and biotechnologies.
