Short Review on Anti-adhesion Coating in Microfluidics for Applications in Biotechnology

Abstract

In this short review, the use of diamond-like carbon (DLC) as anti-adhesion coating in microfluidics is described. The anti-adhesion coating is required on SU-8 based silicon stamp surface to fabricate the polymethylmethacrylate (PMMA) based microfluidic devices using maskless lithography, hot embossing lithography and direct bonding technique. Also, the DLC coating is required on PMMA microchannel surface to change the surface-driven capillary flow of water in PMMA microfluidic devices. The static water contact angle is different on DLC coated PMMA surface with respect to the control PMMA surface. In future, this short review may be useful to fabricate the microfluidic laboratory-on-a-chip systems using diamond-like carbon coating for applications in biotechnology, for example, blood filtering.
