TLDR
In this paper, deoxycholic acid carboxymethyl chitosan (DACMC) was synthesized via a two-step reaction, namely carboxy methylation and alkylation.Abstract:
In the present study, deoxycholic acid carboxymethyl chitosan (DACMC) was synthesised via a two-step reaction, namely carboxymethylation and alkylation. Fourier Transform Infrared (FTIR) Spectrometer, Proton Nuclear Magnetic Resonance (1H NMR) Spectrometer, Transmission Electron Microscope (TEM) and Thermogravimetric Analyser (TGA) were used to characterise DACMC. Spherical self-aggregates of DACMC micelles with the size ranging from 91.3 to 140.0 nm was observed. DACMC was soluble in pH range studied (1–13), except pH 4. DACMC micelles were formed at critical concentration (CMC) value of 0.468 mg/mL. The ability of DACMC to encapsulate and load rotenone was determined at different weight ratios. The highest value of encapsulation efficiency (EE%) (more than 98%) was obtained for weight ratio of 100:1 (DACMC:Rotenone). The in vitro release data of rotenone-loaded DACMC followed Ritger and Peppas Case II transport mechanism. Results from this study highlight the potential of DACMC to reduce organic solvent application in water-insoluble pesticide production.read more
