2.2.3. Microplate reader
The monitoring of OD values and the UV-vis spectra of the bacterial
mixtures used in this work were conducted using a multifunctional
microplate reader (SynergyLX, Biotek/Agilen). The OD measurements were
done on the original mixture of the bacteria with the broth, whilst the
UV-vis spectra were measured for the silver-containing bacteria that
were re-suspended in PBS buffer solutions.
