| Zusammenfassung | In this study, we present a technique that involves depositing a droplet laden with microparticles (μPs) onto a defined sensing area on a microcantilever sensor. This process entailed the optimization of dispensing parameters (pressure p and pulse time t) to the generation of a small water droplet volume (Vd= 53.0 ± 2.72 pL). Subsequently, the evaporation trends of the particle carrier fluid, i.e., the water droplets on the sensor were monitored and a total evaporation time of tev = 40 ± 2 s was determined. By using monodispersed particles in water, i.e., magnetic polystyrene matrix particles (MPS) and poly methyl methacrylate (PMMA) μPs, and adsorbing them on a dynamic cantilever sensor, the mass and number of these μPs were measured and determined comparatively using both resonant frequency measurements and scanning electron microscopy (SEM), respectively. As a result, we have observed and reported monolayer particles assembled on the sensor with a particles count of at least 203. |
