DOI: 10.1002/adhm.201901542
Abstract: The decade-old antibiotic, polymyxin B (PMB), is regarded as the last line defense against gram-negative "superbug." However, the serious nephrotoxicity and neurotoxicity strongly obstruct further application of this highly effective antibiotic. Herein, a charge switchable… read more here.

DOI: 10.1016/j.aca.2021.338208
Abstract: We report for the first time a chronopotentiometric measurement of polyanions based on localized ion depletion at the sample/membrane interface at a characteristic transition time τ, using polymer membrane polyanion-selective electrodes. Chronopotentiometric transduction of polyions… read more here.
