Silk fibroin protein as dual mode picric acid sensor and UV photoactive material

MoS2 / WS2 Nanosheets and Quantum Dots for Sensing Hemin and Fabrication of Self-Powered Photodetectors

“…To predict the mechanism of fluorescence quenching and the interaction between the sensor and analyte, we used the well-known Stern–Volmer (SV) plot in the fluorescence experiments . The SV equation is formulated as follows: I 0 / I = 1 + K SV false[ Q false] where I 0 and I are the fluorescence intensities before and after the addition of the quencher [ Q ].…”

“…The change in the τ value confirms the occurrence of FRET in the system. Moreover, the FRET efficiency can be calculated using the following equation: E = 1 − false( τ DA / τ D false) where τ D and τ DA are the fluorescence lifetime of the donor (sensor) and the donor–acceptor (sensor–analyte) system, respectively. The FRET efficiencies were found to be 26% for MoS 2 NSs, 35% for MoS 2 QDs, 28% for WS 2 NSs, and 34% for WS 2 QDs.…”

Sustainable Macromolecular Materials in Flexible Electronics

“…Silk‐based sensors have been preferred for detecting multiple different phenomena such as optoelectronic characteristics, [ 226 ] and chemical sensor applications. [ 228–230 ] Cai et al.…”

“…[222,223] Silk fabrics have been used as a substrate in silk sensor applications, [224,225] and also added as filling material with its fiber form. [169,170,223,226] In a study by Xu et al, fibrous silk fibroin structures were synthesized by the electrospinning method, and their response against applied pressure was investigated for use in applications such as speech and human motion tracking. [223] In another study, the laser-induced graphene production method was applied on silk fabric, aiming for both low costs in its production and creation of a nature-friendly sensor thanks to the substrate used.…”

“…The resistance change was recorded after the conductive network had been stable after 200 cycles, and the researchers explained the characterization results as their strain sensor being a promising candidate that departed from other commercial and medical contender strain sensors because of high biocompatibility, humidity independent mechanical behavior, and a painless removal process. Silk-based sensors have been preferred for detecting multiple different phenomena such as optoelectronic characteristics, [226] and chemical sensor applications. [228][229][230] Cai et al observed the effect of UV treatment to confirm applicability to the human body, and a decrease in the number of bacteria was reported.…”
