Surface-functionalized hydrophilic monolayer of titanate and its application for dopamine detection†
Abstract
A surface-functionalized hydrophilic charge-neutral monolayer of titanate was exfoliated from the precursor layered composite in aqueous media without addition of a delamination agent. The hydrophilic monolayer was applied for the detection of dopamine based on visible-light absorption originating from charge-transfer excitation from adsorbed dopamine to titanate.
