AgPt/MoS₂ hybrid as electrochemical sensor for detecting H₂O₂ release from living cells

Abstract

Hydrogen peroxide (H2O2), as a biomarker in a series of physiological processes, plays a crucial role in investigating the pathogenesis of some diseases. The highly sensitive and selective detection of...

Ion-modulated photoluminescence of MoS2 nanoflakes for cell viability detection

“…13 Furthermore, 2D MoS 2 nanoflakes with nanoscale lateral dimensions can produce strong fluorescence under ultraviolet light excitation due to the quantum confinement effect. 14 Therefore, 2D MoS 2 nanoflakes possess great potential for developing high-performance optical devices such as solar cells, 15,16 optical sensors, 17 chemical sensing 18,19 and light-emitting diodes. 20,21 However, the applications of PL modulation of MoS 2 in biosensing have not been fully investigated.…”
