Chemical Sensors based on Si Nanowires. Surface modifications for the detection of Ions, explosives and chemical vapors. Promotor: Prof.dr. E.J.R. Sudhölter (TNW).

Chemical sensors play important roles in the environmental monitoring, process control and safety, and medical diagnostics. Silicon nanowires (SiNWs) are very good candidates as the sensing platform due to their unique properties. Surface modification of SiNWs with affinity elements can bring in high sensitivity and selectivity to the detection. This thesis describes the research that has been done on the project of ‘chemical sensors based on SiNWs’, covering the functionalization of SiNWs with ionophores, molecular cages, porous polymers containing nanoparticles for the detection of various analytes present in both the liquid and gas phase. In short, the results presented in this thesis confirm the applicability of sensors that consists of SiNWs for a wide range of chemical sensing applications. It is anticipated that continued advances in the preparation of SiNWs with well-defined structures and defect-free interfaces, the modification of selective and stable affinity or receptor layers on SiNW surface, and assembling larger sensor arrays and integrating them with electronics will lead to exquisite sensor system performances.
