Multifunctional analytical system for determining the characteristics of the optical signal of circular dichroism of a biologically active material

The possibility of creating a multifunctional analytical system (biosensor) based on nanoconstructions (NaC) of DNA (biosensing unit) and a portable dichrometer using light-emitting diodes is discussed. Such a system can work in modes of measuring the optical properties of DNA NaC and calibrating the characteristics of the circular dichroism signal of biologically active substance (BAS) interacting with the biosensing unit, as well as in the mode of measuring the diffusion rate of BAS into the biologically active material of the biosensing unit.
