“…It was observed that a rapid rate of water uptake was observed which increased with time until equilibrium over a period of 600 min (10 h). Cs/PVA blend exhibited high water uptake due to the association/dissociation of the hydrogen bonding between the hydroxyl groups in the PVA and the amino groups in the Cs in the network [24]. It can be also noted that Cs/PVA blend of formulation 2/3 has the highest water uptake (≈ 900%).…”

Abstract:The application of nanotechnology in various fields of science has earned a great concern over the past decades. The natural products and surface-modified polymers and metallic nanoparticles (NPs) have evolved as promising nanomaterials for targeted prostate cancer treatment. In the present study, Chitosan/poly (vinyl alcohol) (Cs/PVA) blend was synthesized by gamma radiation which could behave a nanoreactor for silver (Ag) and gold (Au) nanoparticle with promising anticancer applications. (Cs/PVA/Ag) and (Cs/PVA/Au) nanocomposites were confirmed by SEM (scanning electron microscope) and TEM (transmission electron microscope) analysis. The swelling properties have been investigated as a function of time and pH. The anti-cancer activity of the prepared nanocomposites was demonstrated in prostatic cancer cell line. It has a significant effect against prostatic cancer. However, metal nanoparticles have shown a good experimental success in the field of nanomedicine especially in cancer treatment, which has always been an area of high concern. The collaboration of biomedical research in the identification and characterization of biomedical strategies using the interesting metal nanocomposite will impact the future nanomedicine greatly.

“…Because PMAAc is more hydrophilic than alginate, the MASA31 sample that contained the highest amount of PMAAc among sample showed the highest swelling ratio. The PMAAc/SA IPN hydrogel exhibited temperaturedependent swelling behavior due to the association/dissociation of hydrogen bonding by carboxyl groups in PMAAc and SA within IPN hydrogels (17). A water molecule will gain an enthalpy during an increase in temperature, and the hydrophilic group in the PMAAc/SA IPN hydrogel will be turned into an intramolecular hydrogen bond in this condition (16).…”

A temperature-and pH-responsive interpenetrating polymer network (IPN) hydrogels constructed with polymethacrylic acid (PMAAc) and sodium alginate (SA) by sequential IPN method was studied. The characterizations of IPN hydrogels were investigated by fourier transform infra-red spectroscopy (FT-IR), differential scanning calorimetry (DSC) and swelling tests under various conditions. IPN hydrogels exhibited a relatively high swelling ratio in the range of 183-916% at 258C. The swelling ratio of PMAAc/SA IPN hydrogels depended on pH, temperature and ionic concentration. DSC was used for the quantitative determination of the amounts of freezing and non-freezing water. The amount of free water increased with increasing PMAAc content in the IPN hydrogels.
