Misfolded proteins accumulation in brain results in Alzheimer’s and Parkinson’s disease.1

 Identification of early stage disease biomarker can aid in monitoring and treatability of the disease.

At present, ELISA and other imaging techniques are sophisticated, expensive, time consuming and have low sensitivity.2

In present study, flexible SERS sensor for detection of β-Amyloid Peptide biomarker of Alzheimer’s disease has been developed.3
