This research work describes a non-invasive and label-free immunosensing technique to detect the C-telopeptide of type-I collagen (CTX-1) by Electrochemical Impedance Spectroscopy (EIS). A planar interdigital capacitive sensor is used to evaluate the properties of the material under test. This sensor was fabricated on the basis of thin film micro-electromechanical system (MEMS) semiconductor device...
New types of planar interdigital sensors were fabricated by photolithography and etching techniques on a Silicon/Silicon Dioxide (Si/SiO2) wafer (single side polished). The sensors were then coated with APTES (3-aminopropyltrietoxysilane) a cross linker used to bind Polymyxin B (PmB) molecules on electrodes surface. PmB is an antimicrobial peptide produced by the Gram-positive bacterium-Bacillus which...
