Conducting Polymers for the Design of Tactile Sensors.

This paper provides an overview of the application of conducting polymers (CPs) used in the design of tactile sensors. While conducting polymers can be used as a base in a variety of forms, such as films, particles, matrices, and fillers, the CPs generally remain the same. This paper, first, discusses the chemical and physical properties of conducting polymers.

The application of DNA polymerases and Cas9 as representative of DNA-modifying enzymes group in DNA sensor design (review).

Rapid detection of nucleic acids (DNA or RNA) by inexpensive, selective, accurate, and highly sensitive methods is very important for biosensors. DNA-sensors based on DNA-modifying enzymes for fast determination and monitoring of pathogenic (Zika, Dengue, SARS-Cov-2 (inducer of COVID-19), human papillomavirus, HIV, etc.) viruses and diagnosis of virus-induced diseases is a key factor of this overview.

TiO/TiO-Structure Based 'Self-Heated' Sensor for the Determination of Some Reducing Gases.

In this research we report the gas-sensing properties of TiO/TiO-based hetero-structure, which was 'self-heated' by current that at constant potential passed through the structure. Amperometric measurements were applied for the evaluation of sensor response towards ethanol, methanol, n-propanol and acetone gases/vapours. The sensitivity towards these gases was based on electrical resistance changes, which were determined by amperometric measurements of current at fixed voltage applied between Pt-based contacts/electrodes deposited on the TiO/TiO-based layer.

In-vitro model for assessing glucose diffusion through skin.

Pig ear skin membrane-covered glucose biosensor based on oxygen electrode has been assessed as a tool to evaluate glucose penetration through skin in-vitro. For this, glucose oxidase (GOx) was immobilised on oxygen electrode and covered with the skin membrane. Exposing this electrode to the solution of glucose resulted in glucose penetration though skin membrane, its oxidation catalysed by GOx, consumption of O and decrease of the current of the oxygen electrode.
