Smartphone-Based Electrochemical Biosensors for Directly Detecting Serum-Derived Exosomes and Monitoring Their Secretion

Jing Su et al.

Summary: A sensitive and portable electrochemical biosensor in combination with smartphones was developed for quantitative analysis of exosomes. The biosensor could detect extremely low concentrations of exosomes in microliter-level serum and cell culture supernatant. It also showed great potential for early diagnosis of prostate disease and monitoring of exosome secretion during drug therapy.

Microbial degradation of Procion Red by Pseudomonas stutzeri

Sweta Parimita Bera et al.

Summary: The study investigated the degradation of textile azo dye Procion Red-H3B by Pseudomonas stutzeri SPM-1 isolated from textile wastewater dumping sites in Surat, Gujarat. The optimized conditions led to rapid and efficient decolorization of the dye, along with significant reductions in COD, BOD, and TOC levels in the effluent. The strain exhibited high activities of azoreductase, laccase, and NADH-DCIP reductase, indicating evidence for reductive cleavage of the dye.
