(A) SEM image shows that Salmonella waterborne pathogens are captured by the FGO-PEI based nanoplatform during filtration. (B) TEM image shows that Escherichia coli waterborne pathogens are captured by the FGO-PEI based nanoplatform during filtration. (C) Colony counting data show that Escherichia coli is present in water samples before filtration. (D) Colony counting data show that no Escherichia coli is present in water samples after filtration, which indicates that 100% bacteria is captured during filtration. (E) Salmonella and Escherichia coli waterborne pathogen removal efficiency from drinking water using the FGO-PEI based nanoplatform. For this experiment, we used 103 CFU/mL of each bacterium. (F) Salmonella and Escherichia coli waterborne pathogen removal efficiency from drinking water using the GO-PEI based nanoplatform. For this experiment, we used 103 CFU/mL of each bacterium. G) Salmonella and Escherichia coli waterborne pathogen removal efficiency from drinking water using the FGO based nanoplatform. For this experiment, we used 103 CFU/mL of each bacterium. (H) Escherichia coli waterborne pathogen removal efficiency from tap water, Mississippi river water, lake water, and drinking water using the FGO-PEI based nanoplatform. For this experiment, we used 103 CFU/mL of bacteria infected water samples. (I) Salmonella waterborne pathogen removal efficiency from tap water, Mississippi river water, lake water, and drinking water using the FGO-PEI based nanoplatform. For this experiment, we used 103 CFU/mL of bacteria infected water samples. (J) Simultaneously Salmonella and Escherichia coli waterborne pathogen removal efficiency from tap water, Mississippi river water, lake water, and drinking water using the FGO-PEI based nanoplatform. For this experiment, we used 500 CFU/mL of bacteria infected water samples. (K). Removal efficiency of PFBS, PFBA, tetracycline, and moxifloxacin antibiotics and Salmonella and Escherichia coli waterborne pathogens simultaneously from tap water, Mississippi river water, lake water, and drinking water using the FGO-PEI based nanoplatform. For this experiment, we used water samples infected with 333 ng/L of PFBS, 333 ng/L of PFBA, 333 ng/L of moxifloxacin antibiotics, and 500 CFU/mL of each bacterium. (L) Plot shows how the removal efficiency PFBS, PFBA, tetracycline, and moxifloxacin antibiotics varies with the number of cycles of filtration when we have used the FGO-PEI based nanoplatform in the presence of Salmonella and Escherichia coli waterborne pathogens. For this experiment, we used water samples infected with 333 ng/L of PFBS, 333 ng/L of PFBA, 333 ng/L of moxifloxacin antibiotics, and 500 CFU/mL of each bacterium.
