Pdms toxicity

SpletPolydimethylsiloxane (PDMS) is a commonly used polymer in the fabrication of microfluidic devices due to such features as transparency, gas permeability, and ease of patterning with soft lithography. The surface characteristics of PDMS can also be easily changed with oxygen or low pressure air plasma converting it from a hydrophobic to a ... SpletResults: Biological evaluation for compatibility was carried out and the results showed that the PDMS nanoparticle has no toxicity on RAW 264.7 cells in the concentration range of 10, 20, 40, 60, 80, 100 and 120 μg/mL in culture. Biocompatibility and absence of toxicity was determined by morphological examination and cell viability assays.
