Bacterial Filtration Using Carbon Nanotube/Antibiotic Buckypaper Membranes
Figure 7
Images of LB plates after overnight culture of 100 μL of (a) the initial E. coli suspension, (b) the filtrate obtained after passing the E. coli suspension across a MWNT/Trix membrane, and (c) the filtrate obtained after passing the E. coli suspension across a SWNT/Trix membrane. The initial E. coli suspension was diluted 100,000x before an aliquot was cultured. In the case of the filtrate obtained using an MWNT/Trix buckypaper, no dilution was performed before an aliquot was cultured, while the filtrate obtained using a SWNT/Trix buckypaper was diluted 100x before an aliquot was cultured. In the case of the image in (c) the positions of the cultures have been identified using a black marking pen in order to assist in counting the number of colonies present.
