Surface antimicrobial assay for PDMS and PDMS-PIM materials (PDMS-PIM0.5, PDMS-PIM1 and PDMS-PIM5). Materials have been stored at room temperature for up to 6 months. (A) Surface antimicrobial assay was carried out using representative of Gram negative (E. coli #15036); Gram positive (S. aureus #6538) and Fungi (C. albicans #10231) microbes following the JIS Z 2801–2010 standard protocol at 24 h time point using neat/pure media. (B) Rapid killing efficacy of PDMS-PIM material was carried out based on JIS Z 2801 standard protocol with 30 s exposure of microbes. * denotes zero (0) CFU on the agar plate for undiluted samples. The results are expressed as mean and standard deviation of three replicates
