Interestingly, O2 could promote Ag NPs to be degraded to release more Ag ions, achieving durable bacteriostatic effect. Antibacterial assay demonstrated 6 and 4.49 log unit inactivation toward two typical bacterial strains (E. coli and S. aureus) under Xe arc lamp in 30 min, respectively. Even...
The procedure of iron incorporation didn't change the size and morphology of PCN-224 NPs. The newly formed [email&protected] NPs possessed peroxidase-like activity with much lower Km values and higher Kcat values than most of peroxidase-like nanozymes as well as natural horseradish peroxidase (...
Taking advantage of the excellent peroxidase-like activity of Fe@PCN-224 NPs, we successfully developed a colorimetric method for simple and sensitive detection of hydrogen peroxide and glucose in combination with glucose oxidase.Li, TongHu, PeiLi, JiaweiHuang, PintongTong, WeijunGao, Changyou...
