Enzyme mimics have been developed for bioassay of nucleic acids, with some of them involving complicated labeling. Herein, we report a label-free bioassay for ultrasensitive electronic determination of microRNA at an ultralow concentration based on target-triggered long-range self-assembly DNA-based hybridization

A comparative study between two bisthiosemicarbazones, 2,3-butanedione bis(4,4-dimethyl-3-thiosemicarbazone) and 2,3-butanedione bis(2-methyl-3-thiosemicarbazone), and their copper(ii) complexes is reported. The four compounds have been tested on a leukemia cell line U937 (p53-null) and on an adenocarcinoma cell line A549. The study includes
