A Comprehensive Review on Recent Advances in Chitosan and Graphene Oxide Nanocomposites for Environmental, Biomedical and Smart Material Applications
AI summary Read the abstract
This review summarizes existing research on materials made by combining chitosan with graphene oxide, used for water treatment, medical devices, food packaging, and sensors. It covers how these materials are made and tested, including early work on capturing microplastics, while noting unresolved issues like inconsistent testing methods and unknown long-term safety.
Chitosan–graphene oxide (CS–GO) nanocomposites combine the biodegradability, biocompatibility, cationic character, and film-forming ability of chitosan with the high surface area, oxygen-rich functionality, mechanical reinforcement, and tunable physicochemical properties of graphene oxide, enabling applications in environmental remediation, biomedical engineering, food packaging, sensing, and smart materials. This review critically examines recent advances in CS–GO preparation, interfacial chemistry, characterization, structure–property relationships, sustainability, scale-up, and application performance, with particular emphasis on chitosan molecular weight and degree of deacetylation, GO oxidation level and loading, dispersion, cross-linking, and processing conditions. Hydrogen bonding, electrostatic attraction, covalent coupling, coordination, and π–π interactions govern CS–GO assembly and strongly influence mechanical, adsorption, biological, barrier, electrical, and multifunctional behavior. Environmental remediation and biomedical applications currently have the strongest evidence base, while emerging uses include microplastic capture, desalination, sensing, supercapacitors, proton-exchange membranes, and hydrogen-generation catalysis. Key challenges include inconsistent characterization, limited real-matrix validation, regeneration cost, nanoparticle migration, long-term toxicity, life-cycle impacts, and scalable green manufacturing. Future translation requires standardized characterization, application-specific safety assessment, real-world validation, life-cycle evaluation, and reproducible large-scale fabrication.

Comparative Adsorption of PET and PS Nanoplastics onto Graphene Oxide–Cellulose and Graphene Oxide–Chitosan Composites: Thermodynamic, Kinetic, and Isotherm Studies
AI summary Read the abstract
Scientists tested eco-friendly filter materials made from graphene oxide combined with natural substances like chitosan (from shellfish shells) and cellulose (from plants) to see how well they could pull tiny plastic particles (nanoplastics) out of water. The materials worked especially well at capturing PET nanoplastics, the type of plastic found in water bottles and food packaging, suggesting these low-cost, natural-based filters could one day help remove harmful plastic particles from drinking water before they end up in our bodies.
Adsorption of Polyethylene Nanoplastics by Graphene Oxide–Polysaccharide Composites: Kinetic, Isotherm and Thermodynamic Studies
AI summary Read the abstract
Scientists created sponge-like materials from graphene oxide (a carbon-based material) combined with natural substances like chitosan (from shellfish) and plant fiber to soak up tiny plastic particles from water. The best version removed significant amounts of nanoplastics in lab tests, suggesting this could one day help filter these tiny, hard-to-remove plastic bits out of our water supplies before they reach our bodies. This is early-stage research done in controlled lab conditions, so more work is needed before it could be used in real-world water treatment.
Chitosan-based hybrid composites for emerging organic micropollutants removal from wastewater: Recent advancement, mechanism, up-scaling, and challenges
AI summary Read the abstract
Our tap water and wastewater often contain tiny amounts of drugs, pesticides, and even microplastics that standard treatment plants struggle to remove completely. This review paper rounds up existing research on chitosan—a natural material made from shrimp and crab shells—showing how scientists are turning it into sponge-like filters that can soak up these unwanted pollutants from water. While the technology looks promising, the researchers note it still faces hurdles before it can be scaled up for widespread use in real water treatment facilities.

This review examines how chitosan, a natural material derived from crustacean shells, can be used to remove pollutants including microplastics, heavy metals, and pesticides from wastewater. Chitosan's chemical structure allows it to bind and capture a wide range of contaminants, and it can be combined with other materials to improve its effectiveness. Developing affordable, biodegradable water treatment materials like chitosan could help reduce human exposure to microplastics in drinking water.
