Engineered nanostructures to carry the biological ligands

摘要

Different nanostructures were engineered with the nanoscale dimension lesser than 100 nm. These nanostructures include silver, cellulose nanoparticles and single-walled carbon nanotube (SWCNT). Biological ligands were obtained from the medicinally important herbal plants, such as Solanum trilobatum and Hempedu bumi and conjugated with the nanostructures silver nanoparticle and SWCNT, respectively. On the other hand, bio-ligands from cow urine were encapsulated in the cellulose nanoparticle. To confirm morphology these nanostructures, they were observed under Field Emission Scanning Electron Microscope and the results displayed the uniformed nanostructures. Further, biological ligand carrying ability of these nanostructures was confirmed by the bacterial inhibition assay on the agar plate. This study provided the evidence on the capability of nanostructures to carry the biological ligands.
