A new sensor technology could enable touchless displays that respond to moisture emitted by the human body.
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.
International Year of Light: Whispering Gallery Mode Microcavities
The fundamentals and the advances in the fabrication methods of whispering gallery mode cavities, as well as their application prospects are presented in this review article.
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.
