A Complex of the Electromagnetic Biosensors with a Nanowired Pickup

Abstract EN

The proposal to measure the biosignal values of different origins with advanced nanosensors of electromagnetic quantities is justified when allowing for superconducting abilities of the devices.

They are composed in full-scale arrays.

The said arrays can be both implantable into ionic channels of an organism and sheathed on the sources of the electromagnetic emanation.

Nanowired head sensors function both in passive mode for picking up the biosignals and with additional excitation of a defined biomedium through the same head (in reverse).

The designed variety of bio-nanosensors allow interfacing a variety of biosignals with the external systems, also with a possibility to control the exposure on an organism by artificially created signals.

The calculated signals lies in the range of −5 to 5 V, (7÷0)⋅1017/cm3 molecules or magnetic beads, 2÷10 pH, and stream speed 3⋅10−3÷102 m/s, flow 10−5÷10 m/s, and haemoglobin concentration of 1030÷1024 molec/cm3.

The sensitivity of this micro- or nanoscope can be estimated as HJ=10−4 (A⋅m/√Hz) with SNR equal to 104.

The sensitivity of an advanced first-order biogradiometer is equal to 3 fT/√Hz.

The smallest resolvable change in magnetic moment detected by this system in the band 10 Hz is 1 fJ/T.
