In this study, trigonelline, a niacin-related compound was incorporated into chitosan nanoparticles through ion-complex formation between anionic carboxylic acid group of trigonelline and cationic amine group of chitosan. Morphology of trigonelline-incorporated chitosan nanoparticles have spherical shape with less than 500 nm in size and thier size distribution showed quite unimodel phase. Even though trigonelline and trigonelline-incorporated chitosan nanoparticles were not significantly affected to the proliferation of tumor cells, invasion of tumor cells was effectively inhibited by trigonelline-incorporated chitosan nanoparticles. We suggested that trigonelline-incorporated chitosan nanoparticles are promising candidate for inhibition of tumor cell invasion.

Long-term inflammation and persistent bacterial infection are primary contributors to unhealed chronic wounds. The use of conventional antibiotics often leads to bacteria drug resistance, diminishing wound healing effectiveness. Nanozymes have become a promising alternative to antimicrobial materials due to their low cost, easy synthesis, and good stability.

Liver cancer is a prevalent and significant cause of death in humans. The use of novel biodegradable materials for various biomedical applications is being recently recommended as complementary as well as alternative solution for traditional chemotherapy. This study focuses on the synthesis of biodegradable nanocarriers [chitosan-coated poly(lactic acid) NPs (Cht-PLA NPs)] for the delivery of an anticancer drug vinblastine (Vbx) and to evaluate its therapeutic potential in human hepatocellular carcinoma (HepG2) cells.

Current bacterial infections clinical treatments, such as intravenous antibiotic administration and local injection, suffer from short action duration, repeated administrations, and severe cell toxicity. To address these limitations, it is imperative to develop sustained drug release system with prolonged antimicrobial effects. In this work, a hybrid system was prepared using EDC/NHS catalyzed crosslinking-based carboxymethyl chitosan (CMCS) hydrogel as a carrier to encapsulate biodegradable nanoparticles (NPs) loaded with vancomycin, an efficient antibacterial drug.

Titanium is widely used for implants however it presents limitations such as infection risk, stress shielding phenomenon, and poor osseointegration. To address these issues, a novel approach was proposed that involves fabricating porous titanium substrates, to reduce implant stiffness, minimizing stress shielding and bone resorption, and applying polymeric coatings to improve bioactivity. Composite coating prepared from chitosan, silver nanoparticles, and nanohydroxyapatite was optimized to enhance antibacterial properties and promote osseointegration.
