Design and fabrication of a mould with multiple inserts for a polymeric microfluidic device

Abstract

The present paper reports the design and fabrication of a mould for mass production of a microfluidic device, "opticalstretcher lab-on-chip, a dual-beam optical trap that is used for trapping and deforming micrometer-sized particles.In particular, the mould is designed considering multiple and interchangeable inserts for realizing different microfeaturesadopting different processes. Microchannel, reservoirs and V-grooves have been machined viafemtosecond laser process due its capability to process large surface areas with relatively small depth features andhigh removal rate. On the contrary, complex 3D micro features with high aspect ratio for inverse capillary tubehousing have been manufactured via ?-electro-discharge-machining technology, since fine pulse discharges canbe used to ensure high precision and good surface roughness. Three-dimensional filling numerical analysis hasbeen also performed to improve the device design for the ?-injection moulding process and to set the optimizedprocess parameters. Several prototypes of the Lab-on-chip have been fabricated and experimental tests have beenperformed, showing the feasibility of this technological approach
