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...

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.

Over the years, researchers have looked into several ways to fabricate PDMS to obtain desirable nano-scale and micro-scale features. In this research, a new approach was introduced to fulfill the said requirement for PDMS fabrication. The Intermediate Mold Printing makes use of a commonly available reagent, NOA 81, to form a mold for micro-scale pattern transfer.
