Ultrathin C3N4 nanosheets-based oxidase-like 2D fluorescence nanozyme for dual-mode detection of organophosphorus pesticides

Co-, N-doped carbon dot nanozymes based on an untriggered ROS generation approach for anti-biofilm activities and in vivo anti-bacterial treatment

“…Consequently, they are widely recognized as a paramount global public health menace. [1][2][3] To confront this threat, antibiotics are extensively investigated as a potential remedy for bacterial infections. [4][5][6][7] Nevertheless, an estimated annual death toll of 700 000 individuals is attributed to infections caused by antibiotic-resistant bacteria.…”

Machine Learning-Assisted High-Throughput Strategy for Real-Time Detection of Spermine Using a Triple-Emission Ratiometric Probe

“…6 The integration of deep learning techniques into smartphones allows for personalized applications in smart and portable detection of analytes. 7,8 The teams led by Shen 9 and Liu 10 detected pesticide residues by combining C 3 N 4 nanosheets and metal−organic framework (MOF) fluorescent probes with a smartphone, respectively. Yang et al 11 and Wu et al 12 identified harmful ingredients from food using quantum dot (QD)-and AuAg nanocluster (NC)-based single-signal probes and smartphones.…”

Ratiometric colorimetric detection of nitrite using CoMnO3 nanofibers as an oxidase-like enzyme to induce diazotization reaction

“…On the basis of the outstanding oxidase-like activity of ultra-thin two-dimensional graphite carbonitriding (PtPdNPs@g-C 3 N 4 ), a sensing method for organophosphorus pesticides has been developed. 18 The four-in-one nanocomposite MoS 2 /PDA/CoCu nanozyme was employed for the colorimetric detection of uric acid in human serum and urine samples due to its peroxidase-like activity. 19 Wu et al created ZrO 2 /CeO 2 /polyacrylic acid (PAA) nanocomposites with alkaline phosphatase-like activity that could hydrolyze methyl parathion to p -nitrophenol and tended to be bright yellow.…”
