In this study, an aptamer-based fluorescent sensing platform using triple-helix molecular switch (THMS) was developed for the pesticide screening represented by acetamiprid. The THMS was composed of two tailored DNA probes: a label-free central target specific aptamer sequence flanked by two arm segments acting as a recognition probe; a hairpin-shaped structure oligonucleotide serving as a signal...
Non-small cell lung cancer is the most frequently cause of cancer-related death in the world. To explore the technical feasibility, we detected aberrant promoter methylation of P16 in exhaled breath condensate which was a new, non-invasive tool for diagnosis and screening program of NSCLC.We analyzed aberrant promoter methylation of P16 in 180 samples from 60 individuals, including 30 NSCLC patients...
Nanosized graphene and graphene oxide (GO) are photoluminescent due to the presence of bandgaps and edges/defects. The excellent photostability of these nanomaterials makes them superior to molecular dyes for biological imaging. They can also produce intensive heat under laser irradiation, enabling them to serve as photothermal agents for cancer treatment. In this work, recent studies on the photoluminescence...
