Abstract
We created a cost–benefit analysis and swift point-of-care (PoC) testing for early stage Parkinson’s disease (PD) that delivers the possibility of providing sensitive, rapid, and user-friendly analysis in home diagnostics applications. α-Synuclein (α-Syn) is considered a meaningful biomarker for the diagnosis of early stage PD. The PoC platform for diagnosis of PD is simply constructed with a conductive polymer and an aptamer receptor on a screen-printed electrode and exhibits a remarkable low detection limit of 1 × 10–3 fM. The developed PoC platform will offer an opportunity for individuals to conveniently and periodically check the progress of the diseases and success through expansion as a checkup platform for other diseases.
