Advanced Optical Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 16, 2024

Abstract Detection of colorimetric signals is commonly used in various analytical methods and for testing non‐laboratory resource‐limited settings. The performance assays largely based on nanoparticles their unique optical properties. Multifunctional combining enzyme‐like catalytic properties—known as nanozymes—hold great promise applications signal‐generating labels. However, the extensive focus properties leaves overlooked. In this article, use nanozymes reviewed relying inherent nanozymes, detection a catalytically‐formed product, changes caused by product. impact extinction coefficient reaction products, well kinetic parameters sensitivity limit assays, are quantitatively evaluated. Finally, existing limitations prospects biosensors summarized.

Auriferous Nanozymes: Advances in diagnostic and therapeutic applications

Nanotechnology, Journal Year: 2024, Volume and Issue: 35(50), P. 502003 - 502003

Published: Sept. 25, 2024

Nanozymes are a group of nanomaterials that garnered significant attention due to their enzyme-mimicking properties and catalytic activities comparable those natural enzymes. The ability nanozymes emulate crucial biological processes which can conquer the drawbacks enzymes, such as restricted thermostability well substrate range. Auriferous (gold) possess remarkable enzyme-like properties, reductase, peroxidase, superoxide dismutase, oxidase, catalase. This characteristic makes them strong competitor for possible applications in fields biomedicine biochemical analysis, especially when compared along with simple manufacturing, adaptable features, biocompatibility, affordability. review evaluates factors affect activity auriferous nanozymes. We offer thorough investigation diagnostic applications, including detecting cancer, microorganisms, glucose, cysteine, uric acid. Furthermore, we delve into gold nanozyme therapeutics chemodynamic therapy, radiotherapy, photothermal therapy. In contrast previous review, our highlights various advantages diagnostics therapies provides novel insights diverse encompassing current research studies.
