Micromechanical sensors for the measurement of biopolymer degradation
Publication: Research - peer-review › Article in proceedings – Annual report year: 2011
We present microcantilever-based sensors for the characterization of biopolymer degradation by enzymes. Thin films of Poly(L-lactide) (PLLA) were spray-coated onto SU-8 cantilevers with well-known material properties and dimensions. The micromechanical sensors were immersed in solutions of proteinase K to investigate enzymatic degradation of PLLA. A decrease of the resonance frequency after immersion indicated degradation of the biopolymer coating and allowed the estimation of the degradation rate at a specific enzyme concentration.
