Summary of diameter distributions of Ag NPs in NG determined by cryo-TEM, the weight percent of Ag within the NG as measured by TGA and minimum inhibitory concentration (MIC) of hybrid NGs. D_c is the center of the Log-normal fit.

Sample	Ag diameter (nm) cryo-TEM		Ag wt.% TGA	MIC (μg/mL)
	Ag diameter (nm) cryo-TEM		Ag wt.% TGA	S. aureus		E. coli
