Abstract:
Surface-hydroxylation-induced polarization (SHIP) was shown to promote the cathodic photoelectrochemical (PEC) communication of bismuth oxyiodide with doxorubicin (Dox) by as much as three orders of magnitude. This SHIP tactic was used to establish a polarization electric field (PEF) that not only negatively shifted the conduction band (CB) edge but also promoted the dynamic migration of photogenerated electrons of BiOI to Dox. The tactic underlies a pioneering way to boost signal transduction, and hence offers fresh opportunities for high-performance bioassays.
