Microwell-assisted filtration with anodic aluminum oxide membrane for Raman analysis of algal cells
Abstract(#br)In this study, rapid and direct Raman analysis of microalgae was demonstrated through measurement of algal cells (or algal paste) prepared by microwell-assisted filtration using an anodic aluminum oxide (AAO) membrane. To obtain the algal paste, an array of polydimethylsiloxane (PDMS) microwells with through holes was placed on top of the AAO membrane, after which a vacuum was initiated and a droplet of algal solution dispensed inside the PDMS microwells for a 5-min filtration process.
