Despite their crucial role in healthcare, pharmaceuticals enter water systems through various sources, making them some of the most critical environmental contaminants. Traditional wastewater treatments, which are classified into physical, chemical, and biological techniques, often struggle to effectively remove pharmaceuticals. Among these methods, adsorption stands out as a reliable and versatile approach for removing organic pollutants and enhancing the efficiency of wastewater treatment processes. Biopolymers, particularly chitosan, are gaining attention due to their numerous advantages, including biocompatibility, biodegradability, affordability, high adsorption capability, non-toxicity, and availability from diverse natural sources. Chitosan, a hydrophilic biopolymer, can be chemically modified by incorporating various nanoparticles (e.g., metal oxides, carbon-based materials, and magnetic particles) to boost its adsorption efficiency. These advancements enable chitosan-based nanocomposites to effectively remove a range of pharmaceuticals, including antibiotics, analgesics, and hormones, from water. This review examines the latest developments in chitosan-based nanocomposite adsorbents, emphasizing their fundamental adsorption mechanisms, optimization conditions, kinetic behaviors, and isotherm models. These factors collectively determine the efficiency of nanocomposites in capturing pharmaceutical pollutants. Moreover, the review underscores the potential of these materials for environmental remediation, offering valuable insights into their application and future research directions. Ultimately, the aim of this review is to provide insight into chitosan-based nanocomposite adsorbents, which offer an innovative and effective solution to the challenge of pharmaceutical contamination in water. By addressing key challenges and utilizing advanced material designs, these adsorbents hold great promise for the sustainable and efficient removal of pollutants in environmental systems.</p>","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 13","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143749551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bovine serum albumin nanoparticles (BSA-NPs) can encapsulate significant amounts of hydrophobic substances by attracting charged molecules through electrostatic adsorption. This study aimed to prepare PCA-loaded BSA nanoparticles, producing PCA-BSA-NPs, and subsequently characterize the resulting nanocomposite using zeta potential, dynamic light scattering, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). In vitro, PCA-BSA-NPs were evaluated for their anticancer, antioxidant, and free radical scavenging properties. Our data indicated that the average particle size of PCA-BSA-NPs was 202 nm. The in vitro study demonstrated that PCA-BSA-NPs exhibited potent anticancer activity comparable to doxorubicin. Additionally, PCA-BSA-NPs displayed highly antioxidant activity (2,2-diphenyl-1-picrylhydrazyl (DPPH), superoxide dismutase (SOD) like activity, and catalytic activity) and a strong antidiabetic effect (<i>α</i>-amylase inhibition). The drug release study indicated the effective release of PCA from PCA-BSA-NPs at pH = 6.5, which is suitable for targeting cancer cells. In conclusion, PCA-BSA-NPs could provide a more effective and safer alternative to traditional chemotherapeutic agents like doxorubicin.

Unlike other means of public health tracking, wastewater is independent of individuals having accessibility to healthcare, doctor visits, or infection testing availability. Consequently, raising considerable awareness and complete tracking of infections, including COVID-19 at a community level.
