BIOSENSING DEVICE FOR BIOLOGICAL MICRO- AND NANO-OBJECTS DETECTION Russian patent published in 2017 - IPC C12M1/34 C12Q1/04 G01N29/36 G01N33/48 B82B3/00 

FIELD: biotechnology.

SUBSTANCE: biosensing device for detection of biological micro- and nano-objects, such as bacteria and viruses, is proposed. The device comprises a flat piezoceramic first and second element with flat electrically conductive layers on two opposite sides of each element. At that, one electrically conductive layer of the second element is connected to one electrically conductive layer of the first element, and the electrically conductive layers of the first and second elements not connected to each other are connected to wires for supply or removal of an electrical signal to the device. A sensor layer is also applied to the electroconductive layers of the first and second element not connected to each other. The sensor layer is antibodies specific to the desired biological micro- or nano-object.

EFFECT: increased sensitivity due to reduced threshold of biological micro- or nano-objects detection.
