Advances in electrochemical-optical dual-mode biosensors for detection of environmental pathogens

Analytical Methods, Journal Year: 2024, Volume and Issue: 16(9), P. 1306 - 1322

Published: Jan. 1, 2024

Electrochemical techniques are commonly used to analyze and screen various environmental pathogens. When in conjunction with other optical recognition methods, it can extend the sensing range, lower detection limit, offer mutual validation. Nowadays, electrochemical-optical dual-mode biosensors have ensured accuracy of test results by integrating two signals into one, indicating their potential use primary food safety quantitative assays screening tests. Particularly, visible from electrochemical/colorimetric could meet demand for real-time microbial While probes been receiving increasing attention, there is limited emphasis on design approaches sensors intended Here, we review recent progress merging electrochemical techniques, including fluorescence, colorimetry, surface plasmon resonance (SPR), enhanced Raman spectroscopy (SERS). This study particularly emphasizes reporting performances, principles, types, cutting-edge approaches, applications. Finally, some concerns upcoming advancements briefly outlined.

Aptamer-based therapy for fighting biofilm-associated infections

Journal of Controlled Release, Journal Year: 2024, Volume and Issue: 367, P. 522 - 539

Published: Feb. 3, 2024

Biofilms are key players in the pathogenesis of most chronic infections associated with host tissue or fluids and indwelling medical devices. These hard to be treated due increased biofilms tolerance towards antibiotics comparison planktonic (or free living) cells. Despite advanced understanding their formation physiology, continue a challenge there is no standardized therapeutic approach clinical practice eradicate them. Aptamers offer distinctive properties, including excellent affinity, selectivity, stability, making them valuable tools for purposes. This review explores flexibility designability aptamers as antibiofilm drugs but, importantly, targeting diverse drug delivery systems. It highlights specific examples application species according different modes action inhibition motility adhesion, blocking quorum sensing molecules, dispersal biofilm-cells state. Moreover, it discusses limitations challenges that impaired an success use on biofilm management, well opportunities related modifications can significantly expand applicability field.
