Molybdenum disulfide (MoS2) is a promising catalyst for hydrogen evolution reaction (HER) because of its unique nature to supply active sites in the reaction. However, low density and their poor electrical conductivity have limited performance MoS2 HER. In this work, we synthesized nanosheets on three-dimensional (3D) conductive MoO2 via two-step chemical vapor deposition (CVD) The 3D structure can create structural disorders (referred as MoS2/MoO2), which are responsible providing superior...
In this paper, we report the optoelectronic properties of multi-layered GeS nanosheet (∼28 nm thick)-based field-effect transistors (called GeS-FETs). The GeS-FETs exhibit remarkably high photoresponsivity Rλ ∼ 206 A W−1 under 1.5 μW cm−2 illumination at λ = 633 nm, Vg 0 V, and Vds 10 V. obtained is excellent as compared with a nanoribbon-based other family members group IV–VI-based photodetectors in layered-materials realm, such GeSe SnS2. gate-dependent was further measured to be able...
Multiple sensor systems are designed by varying aza-crown ether moiety in silicon quantum dots (SiQDs) for detecting individual Mg2+, Ca2+, and Mn2+ metal ions with significant selectivity sensitivity. The detection limit of can reach 1.81, 3.15, 0.47 μM, respectively. Upon excitation the SiQDs which coordinated ethers, photoinduced electron transfer (PET) takes place from to valence band core such that reduced probability electron–hole recombination may diminish subsequent fluorescence....
Malaria is one of the major causes morbidity and mortality in developing countries especially Africa. Although over last fifteen years, prevalence malaria became reduced by half but resistance against artemisinin derivatives its combinations, which are only ray hope to treat resistant set back control efforts key hindrance achieve goal elimination till 2030. In spite these artemisinins precious antimalarials, their action mechanism yet be fully understood. Reactive oxygen species (ROS)...
Increasingly, two-dimensional (2D) materials are being investigated for their potential use as surface-enhanced Raman spectroscopy (SERS) active substrates. Hexagonal Boron Nitride (hBN), a layered 2D material analogous to graphene, is mostly used passivation layer/dielectric substrate nanoelectronics application. We have the SERS activity of few-layer hBN film synthesized on copper foil using atmospheric pressure chemical vapor deposition. drop casted probe molecules onto and measured...
Herein, we report ultra-sensitive sensing of a prostate-specific antigen (PSA), which is used as biomarker to detect prostate cancer, using molybdenum series (MoO<sub>3</sub>, MoS<sub>2</sub>, and MoSe<sub>2</sub>) two-dimensional nanosheets (2D NSs).
Abstract Hybrid structures‐based phototransistors are intensively studied recently to achieve high‐performance optoelectronic devices. The hybridization of 2D materials and quantum dots (QDs) is one the ideal platforms for photodetection applications with merits high detection sensitivity wide wavelength coverage. broadband absorption a hybrid device stems from various absorbers multiple bandgaps create photocurrent an efficient exciton generation mechanism under illumination. Here, new...

Melatonin is a potent antioxidant, chemotherapeutic and chemo preventive agent against breast cancer. However, its short half-life one of the major limitations in application as therapeutic drug. To overcome this issue, green-emitting protein nanodot (PND) was synthesized by one-step hydrothermal method for loading melatonin. The pH-7 pH-2 PND showed quantum yield 22.1% 14.0%, respectively. physicochemical characterization both PNDs similar morphological functional activities. Furthermore,...
Aflatoxins (AF) are fungal toxins which not only contaminate food, but also adversely impact human health if consumed and serve as biomarkers for deadly diseases like liver cancer. Therefore, there is a strong need to develop ultra-sensitive AF detection method in physiological environments.
