| Research Abstract |
This work is targeting to produce a single oocyte or donor cell laden droplet on a chip by means of droplet dispensing techniques. The novelty of the present work is that we produce particle-laden droplet by using magnetic micro-actuator (MMT) to achieve the fusion of the oocyte and donor cell on a chip. The main achievement of the work is summarized as follows :
(1) Valve-functioned MMT was successfully chopped droplet and produced size-controlled droplet together with enclosing a particle whose size of 50 μm and transported them one by one. Therefore a wide range of the size of particles or cells can be enclosed in a droplet on a chip.
(2) Hybrid type MMT was successfully fabricated by using high-accuracy Ni metal by electroplating technique. Local rigidity and magnetic property of MMT was successfully controlled and obtained 6 times displacement as large as conventional setting. The revised design chip could have laminar sheath flow or pressure balance which provided on-demand droplet production on a chip successfully.
