From: Gum arabic modified Fe3O4 nanoparticles cross linked with collagen for isolation of bacteria
Scanning electron micrographs (SEM) of various bacterial isolation trials. The trials were performed using 200 μl PBS, 200 μl water, 200 μl collagen and 30 mg Fe3O4. (a) Fe3O4 nanoparticles separated from a solution of 500 μl bacterial (S. aureus) solution (~8-10 cfu/ml) + PBS + water + bare Fe3O4. (b) GA modified Fe3O4 nanoparticles from a solution of 500 μl bacterial (S. aureus) solution (~8-10 cfu/ml) + PBS + water + GA modified Fe3O4. (c) Aggregates of isolated bacteria (S. aureus) and that of the CCGAMION from a solution of 500 μl bacterial (S. aureus) solution (~8-10 cfu/ml) + PBS + water + collagen + GA modified Fe3O4. (d) Fe3O4 nanoparticles from a solution of 500 μl bacterial (S. aureus) solution (~30-40 cfu/ml) + PBS + water + bare Fe3O4. (e) GA modified Fe3O4 nanoparticles from a solution of 500 μl bacterial (S. aureus) solution (~30-40 cfu/ml) + PBS + water + GA modified Fe3O4. (f) Aggregates of isolated bacteria (S. aureus) and that of the CCGAMION from a solution of 500 μl bacterial (S. aureus) solution (~30-40 cfu/ml) + PBS + water + collagen + GA modified Fe3O4. (g) Fe3O4 nano particles from a solution of 500 μl bacterial (S. albus) solution (~30-40 cfu/ml) + PBS + water + bare Fe3O4. (h) GA modified Fe3O4 nanoparticles from a solution of 500 μl bacterial (S. albus) solution (~30-40 cfu/ml) + PBS + water + GA modified Fe3O4. (i) CCGAMION from a solution of 500 μl bacterial (S. albus) solution (~30-40 cfu/ml) + PBS + water + collagen + GA modified Fe3O4. (j) Fe3O4 nanoparticles from a solution of 500 μl bacterial (E. coli) solution (~30-40 cfu/ml) + PBS + water + bare Fe3O4.
