Adhesives Manufacturers Help Microfluidics for Healthcare Electronics Become a Reality

Posted By ASC, Thursday, April 6, 2017

Investment, funding, and research have led to the formulation of non-toxic, low temperature adhesives. These include the development of off stoichiometry thiolene-epoxy (OSTE), allowing microfluidics to become an economically viable field for industries. Microfluidics is becoming a very attractive technology for both academic researchers and industrials since it considerably decreases sample and reagent consumptions,  shortens time of experiments and, in doing so, reduces the overall costs of applications. Thanks to the low volume required, microfluidics represents a promising alternative to conventional laboratory techniques as it allows the achievement of complete laboratory protocols on a single chip measuring just a few square centimetres.

 

Evolving micro-electromechanical systems (MEMS) are leading to interest in wafer packaging and bonding with particular interest in lab-on-chip (LOC) applications. With adhesive bonding being a preferred method in the fabrication of MEMS, the adhesives industry is assisting its clients in exploring new methods of fabrication and bonding.

 

The ability of adhesives to bond dissimilar substrates across a wide range of temperatures while offering the advantage of biocompatibility is changing the wafer packaging market allowing the development of low-cost devices for immunoassays and DNA analysis. Adhesives for microfluidics are currently still in their infancy with niche technology status, but with research in the Asia-Pacific region making it a wafer packaging hub, attempts are being made to optimize the production of MEMS. This will lead to a greater demand for adhesives able to achieve shorter cure times, greater homogeneity and improved uniformity.
