Special Issue Information

Dear Colleagues,

The topic represents a cutting-edge area of research at the intersection of nanotechnology and biotechnology. These biosensors leverage the unique properties of micro/nanomaterials to enhance sensing capabilities, enabling highly sensitive and selective detection of biological analytes.

Key advancements include the development of novel fabrication techniques for micro/nanomaterials, such as graphene, carbon nanotubes, hydrogel, DNA nanostructures, and metal nanoparticles, which offer enhanced surface area, biocompatibility, catalytic activity, optical activity, and conductivity.

Additionally, integration with biological recognition elements, such as enzymes, antibodies, and nucleic acids, further enhances biosensor performance. These advancements hold promise for applications in various fields, including medical diagnostics, environmental monitoring, and food safety.

Tylosin (TYL) is a macrolide antibiotic widely used in animal husbandry. Due to associated health risks, there is a demand for sensitive methods for mass screening of TYL in products of animal origin. This article describes the development of lateral flow immunoassays (LFIAs) for TYL detection using direct (anti-TYL antibodies conjugated with nanoparticles) and indirect antibody labeling (anti-species antibodies conjugated with nanoparticles and combined with native anti-TYL antibodies). The choice of LFIA conditions, such as concentrations of hapten–protein conjugates, specific antibodies, and gold nanoparticle (GNP) conjugates with antibodies, as well as incubation time of reagents and the concentration of detergent in the sample buffer, is presented. The achieved limits of TYL detection using LFIAs with indirect labeling were 0.8 ng/mL (visual) and 0.07 ng/mL (instrumental), compared to 4 ng/mL (visual) and 0.4 ng/mL (instrumental) for the case of direct labeling. The sensitivity of the LFIA using the indirect format was up to seven times higher, allowing the determination of the target analyte at low concentrations. TYL detection in ground meat using LFIA with indirect antibody labeling ranged from 76–119%. Full article
