Prostate cancer (PCa) is a leading cause of cancer-related death among males globally. To date, prostate-specific antigen (PSA), as a typical tumour marker, has been widely used in the early diagnosis of PCa. However, in practical clinical tests, high serum levels of PSA show a high probability for false-positive results, leading to misdiagnoses. In this study, we developed a new classification system...
A novel rhodamine based sensor RBH was developed and synthesized by rhodamine B with 3-methyl-2-benzothiazolinone hydrazone, which exhibited high selectivity and sensitivity for sensing Cu2+ ions in the presence of other important relevant metal ions in aqueous acetonitrile. As an “off-on” fluorescent sensor, RBH exhibited a UV–vis absorption increase at 570 nm and a 132-fold significant fluorescence...
A novel coumarin derivatives based fluorescent chemosensor CBH was designed and synthesized by Schiff base reaction, which was connected by 7-(N,N-diethylamino) coumarin-3-aldehyde and 3-methyl-2-benzothiazolinone hydrazone through C=N. X-ray single crystal structure analysis indicated that two aromatic groups of the CBH were almost in the same plane. It displayed enhancement of the fluorescent intensity...
