The method according to the invention consists in providing a wafer having a bottom layer, a top first sacrificial layer and an insulating layer, structuring the first sacrificial layer to form a three dimensional structure onto which a first structural layer is deposited to define a corresponding three dimensional structure on the bottom surface of the first structural layer. The method consists also in forming a second three dimensional structure on the upper surface of the first structural layer.

Method for producing microcarriers and for performing biological assays

The present invention relates to a method for producing microcarriers comprising the following steps: (a) providing a wafer having a sandwich structure comprising a bottom layer, a top layer and an insulating layer located between said bottom and top layers, (b) etching away the top layer to delineate lateral walls of bodies of the microcarriers, (c) depositing a first active layer at least on a top surface of the bodies, (d) applying a continuous polymer layer over the first active layer, (e) etching away the bottom layer and the insulating layer, (f) removing the polymer layer to release the microcarriers.

Method for producing microcarriers

The present invention relates to a method for producing microcarriers, the method comprising the steps of providing a wafer having a bottom layer, a top layer and an insulating layer, structuring the top layer to define at least one three-dimensional structure on the top surface of the top layer, etching away the top layer to delineate lateral walls of bodies of the microcarriers, applying a continuous polymer layer over the top surface of the bodies of the microcarriers, removing the bottom layer and the insulating layer, structuring the bottom surfaces of the bodies of the microcarriers to define at least one three-dimensional structure on the bottom surface of each body, and removing the polymer layer to release the microcarriers.

Method for producing structured microcarriers

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.
