“…2(3) The increase of mass at the QCM surface brings about the increase of inductance value. As a result, the value of frequency resonance will decrease since the frequency is in reverse with the inductance (Sakti et al, 2018). This is shown by the move of the minimum peak toward the left direction in the frequencyimpedance graph.…”

“…The smallest surface toughness occurs when the biggest layer concentration is 3%. In numerous applications, the sensor surface is made flat to avoid damping effect (Deniz & Deligöz, 2019;Masruroh et al, 2014;Sakti et al, 2018). Therefore, the optimum concentration parameter for PS layer above the QCM surface should be 3%.…”

“…The frequency of QCM resonance alteration due to the change of mechanical characteristics of the material is linked to the dissipation of acoustic energy and the transmission of the acoustic wave inside the material (Masruroh et al, 2014;Sakti, Masruroh, Sabarudin, Santjojo, &Khusnah, 2018). When resonance takes place, QCM oscillator can be assumed to be in an electrical circuit frequently called Butterworth-van Dyke (BVD) model.…”

“…The thickness of monolayered protein due to absorption is relatively smaller in comparison to the length of acoustic wave triggered by the sensor (Sakti et al, 2018;Yang, Li, Chen, & Mercadé-prieto, 2017). Since the formed layer is really thin, while the threshold frequency is really high, the antigen/antibody can be assumed to form a thin layer.…”

Polystyrene (PS) thin film with various concentration of mass (1%, 3%, and 5%) has been deposited onto Quartz Crystal Microbalance (QCM) surface by a spin coating method. The purpose of this research is the improvement of Bovine Serum Albumin (BSA) immobilization into the QCM surface. The QCM resonance frequency has been investigated by means of Impedance Analyzer. The film thickness was calculated by the Sauerbrey equation. The surface roughness of the PS layer was observed by noncontact Topography Measuring System (TMS-1200). Calculation result using a Sauerbrey equation shows the thickness of the PS layer increases with the increasing PS concentration. The QCM/PS with 1% and 5% concentration of mass has rougher morphology and more frequency shifts caused by BSA injection compared to 3% concentration of PS

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.
