Magnetic polymer composite-based microvalves. Fabrication of magnetically driven microvalve arrays using a photosensitive composite: (a) materials, (b) fabrication process (step 1: exposure to UV light, step 2: development, step 3: released microvalve), and (c) operation principle of the magnetically controlled microvalves (reproduced and adapted with permission from Magnetochemistry MDPI) [85]. (d) Microvalves based on a ferrowax composite, for an automated diagnostic microsystem involving serial dilution processes (reproduced with permission of the authors and Authorae) [86].
