Evaluation of interactions of multi-walled carbon nanotubes with benzoic acid and its 2-halogeno derivatives and their cytotoxicity: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


On this examine, interactions of multi-walled carbon nanotubes (MWCNTs) with benzoic acid and 2-halogeno (F, Cl and Br) derivatives had been investigated. As well as, these compounds had been decided to be cytotoxic on Main Peripheral Blood Mononuclear cells. Adsorption percentages of MWCNTs uncovered to those acids on the similar focus for 24 hours had been calculated. Raman spectroscopy, Fourier Remodel Infrared Spectrocsopy (FT-IR) and Scanning Electron Microscope (SEM) methods had been used to find out the chemical and bodily adjustments attributable to acid species on the construction of MWCNTs. On account of the investigations, it was decided that 2-bromobenzoic acid (BrBA) was adsorbed most favorably by the construction. The construction adsorbed the benzoic acid derivatives higher than benzoic acid (BA). The least defect occurred within the pattern subjected to BrBA. It was discovered that there was no correlation between absorption charges and defect occurrences within the construction. SEM outcomes point out aggregation, tube curl, and filling in inter-tube areas in samples the place absorption is intense. In FT-IR spectra of all constructions obtained, the attribute vibration band associated to MWCNTs, and C = O stretching vibration band of the benzoic acid and its derivatives had been noticed round 1450 and 1680 cm−1, respectively.
