Fast Release

Fast temperature-responsive interpenetrating polymer network hydrogels based on soy protein and poly(N-isopropylacrylamide) (PNIPAAm) were prepared using the sodium bicarbonate (NaHCO3) solutions as the reaction medium. The structure and properties were characterized using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The bovine serum albumin (BSA) release behaviors and release mechanism were also investigated. The results show that the proposed hydrogels have high porous structures and have a fast release rate. The BSA release mechanism belongs to an anomalous transport and the Fickian contribution is dominant. The proposed hydrogels may have the potential applications in the field of biomedical materials such as in the controlled release of drugs.

In this work, porous biochar was obtained from sugarcane bagasse by alkali activation and pyrolysis and then magnetized with γ-Fe2O3 by calcination. After functionalization with chitosan and activation with glutaraldehyde, the as-prepared chitosan/magnetic porous biochar served as a support to immobilize cellulase by covalent bonds. The immobilization amount of cellulase was 80.5 mg cellulase/g support at pH 5 and 25 °C for 12 h of immobilization. To determine the enzymatic properties, 1% carboxymethyl cellulose sodium (CMC) (dissolved in 0.1 M buffer) was considered as a substrate for hydrolysis at different pH values (3–7) and temperatures (30–70 °C) for 30 min. The results showed that the optimum pH and temperature of the free and immobilized cellulase did not change, which were pH 4 and 60 °C, respectively. The immobilized cellulase had a relatively high activity recovery of 73.0%. However, it also exhibited a higher Michaelis–Menten constant (Km) value and a slower maximum reaction velocity (Vmax) value compared to the free enzyme. In the reusability assay, the immobilized cellulase showed initial glucose productivity of 330.9 mg glucose/g CMC and remained at 86.0% after 10 uses. In conclusion, the chitosan/magnetic porous biochar has great potential applications as a support for enzyme immobilization.
