Electrochemistry of proteins at the interface between two immiscible electrolyte solutions
MetadataShow full item record
The electrochemistry of proteins at the interface between two immiscible electrolyte solutions (ITIES) is discussed, with detection capabilities based on protein-facilitated anion transfer, and which has enabled protein detection via adsorptive stripping voltammetry. Targeting an enzymatic biomarker has achieved detection at picomolar concentrations, whilst studies into structural aspects of proteins at the ITIES have revealed formation of oligomers (cytochrome c) and unfolded protein (lysozyme) together with alterations to the protein secondary structures.

A randomised controlled trial of twelve months protein supplementation on muscle mass and strength in elderly womenMeng, Xingqiong (Rosie) (2010)Background. Aging is associated with progressive loss of muscle (sarcopenia), which can lead to reduced muscle strength and an increased risk of falls. Sarcopenia exists in otherwise healthy elderly people and its aetiology ...
