Fabrication and characterisation of intermediate mold printing using laser-processed PMMA substrate

The rising interest in microfluidic studies in biological research has widened up the search for a variety of biocompatible materials. There are several materials available in the market, with Polydimethylsiloxane (PDMS) being the most common one. An expensive and slow process, the soft lithography...
