Engineering an Ionic Aggregation-Induced Luminescence-Labeled Fluorescence Lateral Flow Immunoassay for C-Reactive Protein in Human Plasma.

The surge of lateral flow immunoassays (LFAs) stimulates researchers to explore the novel vibrant aggregation-induced emission luminogen (AIEgen)-doped nanoparticles to improve the accuracy and reliability of LFAs. However, the loading amount of AIEgens currently used for the LFA in microspheres is limited due to their symmetrical large conjugated skeleton structure, which significantly reduces the fluorescence brightness of the signal reporter in the LFA. Herein, an ionic AIEgens with a donor-acceptor type was developed as the signal reporter of the LFA for C-reactive protein (CRP).

An electrochemical aptasensor for methylamphetamine rapid detection by single-on mode based on competition with complementary DNA.

A simple and rapid electrochemical sensing method with high sensitivity and specificity of aptamers was developed for the detection of methylamphetamine (MAMP). A short anti-MAMP thiolated aptamer (Apt) with a methylene blue (MB) probe at 3'-end was immobilized on the surface of a gold electrode (MB-Apt-S/GE). The electrochemical signal appeared when MAMP presenting in the sample solution competed with cDNA for binding with MB-Apt-S.

Trace Amounts of CoO Nano-Particles Modified TiO Nanorod Arrays for Boosted Photoelectrocatalytic Removal of Organic Pollutants in Water.

Trace amounts of CoO modified TiO nanorod arrays were successfully fabricated through the photochemical deposition method without adding any nocuous reagents. The CoO/TiO nanorod arrays fabricated in acid solution had the highest photo-electrochemical activity. We elaborated on the mechanism of CoO-TiO fabricated in different pH value solutions.
