Synthesis and Characterization of pH-Sensitive Poly (N-isopropylacrylamide-co-acrylic Acid) Hydrogels for Controlled Release of Doxorubicin
Abstract: pH-responsive polymeric hydrogels have attracted significant attention as intelligent biomaterials for site-specific and controlled drug delivery in cancer therapy due to their ability to respond to the acidic tumor microenvironment. In the present study, poly (N-isopropylacrylamide-co-acrylic acid) [P(NIPAM-co-AAc)] hydrogels were synthesized via free radical copolymerization and systematically characterized to evaluate their suitability for controlled delivery of doxorubicin, a widely used chemotherapeutic agent. The copolymer hydrogels were prepared using N-isopropylacrylamide and …

Effect of Polymer Crosslinking on Drug Release Kinetics
Abstract: In order to improve treatment effectiveness and minimise adverse effects, polymer-based drug delivery systems are often used to produce regulated and sustained drug release. Polymer crosslinking, which alters the structural, mechanical, and degrading characteristics of the polymer matrix, is one of the key elements affecting drug release kinetics. The porosity, swelling behaviour, and rate of degradation of the polymer are all impacted by the crosslinking process, which may be accomplished …

Cosmetic Topical Formulations: Design Strategies, Skin Interaction Mechanisms, Clinical–Cosmetic Applications, and Emerging Trends
Abstract: Cosmetic topical products are central to modern skin care, as they deliver active ingredients directly to the skin surface and upper layers to improve appearance, texture, and function. By acting locally on the epidermis and adnexal structures, these preparations help manage dryness, photoaging, pigmentation, acne, and sensitive-skin conditions while minimizing systemic exposure. A wide range of dosage forms—creams, lotions, gels, ointments, serums, sprays, and transdermal-inspired cosmetic patches—are engineered to modulate …
