Опубликована: Янв. 21, 2025

As one of the most harmful heavy metal pollutants, hexavalent chromium Cr(VI) is becoming a serious threat to human health. Thus pursuing remarkably sensitive method monitor concentration in natural conditions favored for fast response prevent harm. In present work, an ethylenediamine (En) and SiO2-modified wool keratin-based carbon quantum dot (CQD)(En@CQDs@SiO2) fluorescent sensor prepared, En found improve discrimination ability by binding with surface carboxyl groups. Based on these designs, En@CQDs@SiO2 achieves significant improvement detection ability, limit 6.08 × 10–4 mg/L, which succeeded 6 times over CQDs, better than conventional UV–Vis flame atomic absorption (AAS) techniques. Furthermore, has good relative sensitivity, selectivity, spectral reproducibility, excellent structural stability. These properties make suitable environmental detection, undoubtedly improves economy friendliness sensor.

Sustainable Approaches for Pharmaceutical Pollutant Removal: Advances in Chitosan‐Based Nanocomposite Adsorbents

ChemistrySelect, Год журнала: 2025, Номер 10(13)

Опубликована: Апрель 1, 2025

Abstract The growing presence of pharmaceutical pollutants in aquatic environments poses significant threats to both human health and ecosystems. Despite their crucial role healthcare, pharmaceuticals enter water systems through various sources, making them some the most critical environmental contaminants. Traditional wastewater treatments, which are classified into physical, chemical, biological techniques, often struggle effectively remove pharmaceuticals. Among these methods, adsorption stands out as a reliable versatile approach for removing organic enhancing efficiency treatment processes. Biopolymers, particularly chitosan, gaining attention due numerous advantages, including biocompatibility, biodegradability, affordability, high capability, non‐toxicity, availability from diverse natural sources. Chitosan, hydrophilic biopolymer, can be chemically modified by incorporating nanoparticles (e.g., metal oxides, carbon‐based materials, magnetic particles) boost its efficiency. These advancements enable chitosan‐based nanocomposites range pharmaceuticals, antibiotics, analgesics, hormones, water. This review examines latest developments nanocomposite adsorbents, emphasizing fundamental mechanisms, optimization conditions, kinetic behaviors, isotherm models. factors collectively determine capturing pollutants. Moreover, underscores potential materials remediation, offering valuable insights application future research directions. Ultimately, aim this is provide insight offer an innovative effective solution challenge contamination By addressing key challenges utilizing advanced material designs, adsorbents hold great promise sustainable efficient removal systems.

Cell Death Mechanisms Produced by Carbon‐Based Nanoparticles

Journal of Nanotechnology, Год журнала: 2025, Номер 2025(1)

Опубликована: Янв. 1, 2025

Using carbon‐based nanoparticles, such as diamond, graphite, fullerene, and nanotubes, has increased their research possible strategies for drug delivery to control diseases, especially cancer. However, because these materials, when interacting with the living environment, release substances that are capable of inducing cell death by themselves, it is vital importance analyze type particle can induce. Although there different efforts describe kind nanoparticles used treat diseases cancer, no paper explains mechanisms induced nanoparticle systems. Therefore, this attempts gain cutting‐edge information on using nanopolymorphisms mechanism particles produce. In conclusion, carbon interact directly membranes, causing physical damage disturbing integrity membrane. This alteration mainly lead necrosis or apoptosis. The definition a predominant each depends dose‐dependent manner. Primarily, concentrations cytotoxicity were 100–500 μg/mL. several studies analyzed, was only find nanodiamonds proved not be cytotoxic.
