Fabrication of micro-mechanical sensors with the polymer SU-8
In this paper, we present the design and fabrication of biosensors based on SU-8 cantilevers with a thickness ≤ 5μm. The processing of the polymer was optimized to reduce initial bending of the devices which is essential for optical read-out of the cantilever deflection. Solvent absorption in the SU-8 had to be minimized to reduce drift of the cantilever bending during measurements in liquid. The
