Gold nanoparticles (AuNPs) exhibit several unique properties including redox activity, surface plasmon resonance, a high surface-to-volume ratio, or spontaneous formation of a stable Au-S dative bond with biological thiols. Biothiols are endogenous compounds that play a significant role in biological systems and their altered levels have been associated with disease states. However, levels of biothiols are low in non-invasive biological samples such as saliva or exhaled breath condensate (EBC). In this work, AuNP synthesis and AuNP-based extraction of biological thiols from samples followed by CE-LIF analysis are investigated.
