This review provides a general overview of different biosensors, mostly concentrating on electrochemical analytical devices, while briefly explaining general approaches to various kinds of biosensors, their construction and performance. A discussion on how all required components of biosensors are brought together to perform analytical work is offered. Different signal-transducing mechanisms are discussed, particularly addressing the immobilization of biomolecular components in the vicinity of a transducer interface and their functional integration with electronic devices. The review is mostly addressing general concepts of the biosensing processes rather than specific modern achievements in the area.

A cost-effective strategy is reported utilizing ionic liquid (IL), 1-hexyl-3-methylimidazolium bisulfate ([HMIM] HSO), to delaminate TiC MXene, thereby enhancing its efficiency in electrocatalyzing tryptophan (Trp) oxidation. The positively charged IL effectively intercalates within the negatively charged MXene layers, fostering structural stability through π-π stacking and electrostatic interactions. Consequently, the resulting IL-TiC composite not only maintained the inherent electronic conductivity of TiC but also significantly augmented its electrocatalytic prowess.

Deoxynivalenol (DON) is one of the most harmful mycotoxins that poses great health threats to human and animals. Herein, a simple and sensitive magnetic beads-based fluorescent biosensor was successfully prepared for detection of DON in cereals. A stable double-stranded DNA (dsDNA, biotin-sDNA+FAM-cDNA/AP) was formed on the surface of streptavidin-coated magnetic beads (SMBs).

Infectious bronchitis virus (IBV), an avian coronavirus, member of the genus Gammacoronavirus, poses significant threats to poultry health, causing severe respiratory, reproductive, and renal infections. The genetic diversity of IBV, driven by mutations, recombination and deletions, has led to the emergence of numerous serotypes and genotypes, complicating both diagnosis and control measures. Rapid and accurate diagnostic tools are essential for effective disease management and minimizing economic losses.
