Abstract

Silicon microcarriers suitable for fluorescent assays as a well as a method of producing such microcarriers are provided. The method includes the steps of providing a SOI wafer having a bottom layer of monocristalline silicone, an insulator layer and a bottom layer of monocristalline silicon, delineating microparticles, etching away the insulator layer and then depositing an oxide layer on the wafer still holding the microparticles before finally lifting-off the microparticles.
