Laser micro-engineering of functionalised cyclic olefin polymers for microfluidic applications

摘要: Direct-write laser processing has been demonstrated to be capable of both surface patterning micro- and nanoscale structures on polymer surfaces without significant modification the chemistry or optical transmission processed area. In this work, creation microchannels via direct-write 188 μm thickness cyclic olefin polymers is demonstrated, along with a route towards channel functionalization. Cyclic (COP) are an emerging class noted for their high chemical resistance, biocompatibility higher transparency when compared other common polymers. These properties make them excellent substrates fabrication microfluidic devices. This paper presents first investigation into infrared COP using 1064 nm Nd:YAG laser. Scanning electron microscopy Raman spectroscopy were utilized investigate morphology composition these textured surfaces. A functionalization biological speciation separation was examined carbon nanoparticles. The nanoparticles produced pulsed ablation in liquid (PLAL) which reported as fast adaptable method nanoparticle production. while coating CNPs SEM. results discussed context development new achieving optimized microfluidicbased separations speciation.
