A Flexible and Sensitive miRNA Biosensor
Low concentrations (10 × 10−15 M) of the disease biomarker microRNA-21 (miRNA-21) can be detected by a flexible biosensor.
A Fluorescent Rotaxane: Molecular Shuttle and Sensor Gel
The fluorescent rotaxane is a molecular shuttle sensitive to temperature, pH, and solvent polarity changes. It forms a gel which changes its fluorescence properties upon acidic/basic gas exposure and can be turned into a liquid by shaking, heating, and by adding anions.
Facile, Green, and Tunable: Synthesizing Catalytically Active Multimetallic Mesoporous Spheres
A facile, green, and tunable synthesis for mesoporous spheres consisting of noble metals is developed. The spheres are potential catalysts in fuel cells.
Spacer Layers Enhance Organic Photovoltaic Performance
Inserting a spacer layer between the donor and the acceptor material of organic photovoltaic (OPV) devices enhances their power conversion efficiency.
Biosensor for Oral Cancer Detection in Saliva
A simple, sensitive, and noninvasive biosensor for oral cancer (OC) detection in saliva based on antibodies attached to zirconium oxide on indium tin oxide glass.
Face the Edges: Edges of nanomaterials
Edges of nanomaterials show special and exciting properties and are important for the performance of catalysts or for materials such as graphene.
Photoanodes for Efficient Water Splitting by Photoelectrochemical Cells
Novel hematite-derived photoanodes for photoelectrochemical (PEC) cells improve the efficiency of solar energy storage by water splitting.
