- Abstract
In this work, Quartz Crystal Microbalance (QCM) has been coating by Polystyrene (PS) and Zinc Phthalocyanine (ZnPc). This study aimed to examine the effect of coating using PS and ZnPc on the immobilization ability of QCM towards Bovine Serum Albumin (BSA) biomolecule. Polystyrene was used to coat the surface of QCM using Spin Coater technique, while ZnPc was coated by means of vacuum evaporation method. Surface characterization was performed using Scanning Electron Microscope (SEM) and Atomic Force Microscope (AFM), the QCM impedance was measured by using Impedance Analyzer; while the changes on its frequency was gauged by using frequency counter. Drawing on the SEM results, it was unveiled that PS layer was coated densely, while ZnPc was coated with full of roughness. The roughness of the PS and ZnPc layer was 244 nm and 88.9 nm respectively.
