Disposable polymeric micro-cantilever arrays for sensing

To fabricate low-cost polymeric cantilever arrays, we have applied injection molding. For polymers, including polypropylene and polyvinylidenfluoride, cantilever dimensions in the micrometer range with an aspect ratio as large as 10 were successfully manufactured. The cantilevers show a performance similar to the established silicon cantilevers. Combined with functionalization, the cantilever arrays show a great potential in biomedical applications.
