“…Moreover, peptides have become an effective and important alternative to antibodies as bioreceptors in the development of novel diagnostic tools, while providing several advantages owing to their stability, ease of synthesis, and the engineering of their structure [3]. Among others, these properties help in decreasing the steric hindrance of the receptors, thus allowing the increase in active sites to capture the analytes of interest, leading to an enhanced sensitivity of the biosensing platforms toward several bio-and non-bio molecules, such as heavy metals (lead, mercury, and cadmium), DNA, peptides, cells, and proteins [4][5][6]. The application of peptides as bioreceptors to detect target proteins and antibodies is well known, as witnessed by the high number of methodologies and tools used in clinical diagnostics and medical surveys [7].…”
