Gold nanomaterials for biochemical sensing

Plasmonic quenching and enhancement: metal–quantum dot nanohybrids for fluorescence biosensing

“…Section 3.1), PQF of QDs via metal nanomaterials has been largely dominated by AuNPs. Many review articles that discuss and summarize biosensing via NSET from different fluorophores (including QDs) to AuNPs 13,14,[75][76][77][78][79][80] and, in particular, from QDs to AuNPs 18,21,61,[81][82][83][84] have been published over the last 10 years. Recently, we also reviewed the actual energy transfer mechanism and the use of both terms (NSET or FRET) within different bioanalytical studies using QDs and other fluorophores as donors.…”

Electrochemical investigations and antimicrobial activity of Au nanoparticles photodeposited on titania nanoparticles

“…Fig. 5 illustrates how the activation/stabilization cyclic voltammetry scans of nano-sized metal electrodes on a Pt polycrystalline electrode reveal the widely recognized gold behavior when used in an extremely acidic solution [ 85 ]. The layer was lowered within the cathodic sweep at a potential of approximately 0.896 V. The development of a thin oxide layer on the outside of gold drives the oxidation reaction at a high voltage (1.3 V).…”

Development of a Fluorescent Biosensor Based on DNAzyme for Tracing the Release of Zinc in Maize Leaves

“…With the rapid development of nanotechnology, a vast application potential of diverse nanomaterials has been exploited due to their extremely small size, wide range of suitable properties, and easy modification. , Zinc oxide nanoparticles (ZnO NPs) are one of the most common engineered nanomaterials that can be produced on a massive scale by a simple synthesis route. They have been proposed as drug delivery carriers, antibacterial agents, and key components in biochemical sensors. − Moreover, ZnO NPs can be used as a new fertilizer for plants in the field of bio-agriculture application, because they are proven to be more easily absorbed by plants .…”
