I posted details earlier in another thread: Inventions and attempted inventions - #4 by Enon
I’ll give some key bits from the paper cited there:
after incubation with E. coli, the Ag/TA-coated textile and uncoated textile were left to sit in LB growth media overnight, and the OD600 of the uncoated textile (high turbidity) was at least 2-log [100x] higher than that of the Ag/TA-coated textile(transparent), with OD600 values of 26.6 vs 0.1 for paper, 2.21 vs 0.01 for silk, and 27.3 vs 0.27 for polyester, respectively
This was a test measuring the number of bacteria in a growth medium by the scattering or turbidity of the medium after the bacteria incubated overnight.
