Parametric study of protein solution evaporation inside the microwells for micropatterning
Abstract(#br)In this study, evaporation of bovine serum albumin aqueous solution (BSA (aq) ) inside microwells was investigated. A droplet of BSA (aq) was dispensed on a cleaned glass slide, followed by placing a polydimethylsiloxane (PDMS) stamp with microwell array on top of the droplet. Different deposited structures at micro/nano scale were obtained after complete evaporation of the solution. The operating parameters such as the dimensions of the microwells and solution concentrations were studied. It is found that, at lower solution concentration ( e.g.
