“…It is well known that algae growing in metal-polluted environments could have a toxicological content. Several studies focusing on the chemical composition of the Sargassum species showed also their possible heavy metal content [ 37 ]. Therefore, further studies conducted with novel detection frameworks are needed to clarify the heavy metal toxicity properties of the presented biomaterial herein [ 38 ].…”

Marine Algae Incorporated Polylactide Acid Patch: Novel Candidate for Targeting Osteosarcoma Cells without Impairing the Osteoblastic Proliferation

Biodegradable collagen-based materials have been preferred as scaffolds and grafts for diverse clinical applications in density and orthopedy. Besides the advantages of using such bio-originated materials, the use of collagen matrices increases the risk of infection transmission through the cells or the tissues of the graft/scaffold. In addition, such collagen-based solutions are not counted as economically feasible approaches due to their high production cost. In recent years, incorporation of marine algae in synthetic polymers has been considered as an alternative method for preparation grafts/scaffolds since they represent abundant and cheap source of potential biopolymers. Current work aims to propose a novel composite patch prepared by blending Sargassum vulgare powders (SVP) to polylactide (PLA) as an alternative to the porcine-derived membranes. SVP-PLA composite patches were produced by using a modified solvent casting method. Following detailed material characterization to assess the cytocompatibility, human osteoblasts (HOBs) and osteosarcoma cells (SaOS-2) were seeded on neat PLA and SVP-PLA patches. MTT and BrdU assays indicated a greater cytocompatibility and higher proliferation for HOBs cultured on SVP-PLA composite than for those cultured on neat PLA. SaOS-2 cells cultured on SVP-PLA exhibited a significant decrease in cell proliferation. The composite patch described herein exhibits an antiproliferative effect against SaOS-2 cells without impairing HOBs’ adhesion and proliferation.

“…The Nemero Pollution Index (PN) was used to determine the total pollutants in the soil [35], which revealed that the soil in the area was seriously polluted. Except Ni (PN = 0.35), the PN value of all other heavy metal elements is greater than or equal to 0.7.…”

Yangchun City, a typical polymetallic ore distribution area in Guangdong Province (China), was selected as the research region to study the content, distribution, source, and possible impacts of heavy metals (HMs) (Arsenic: As; Cadmium: Cd; Chromium: Cr; Copper: Cu; Mercury: Hg; Nickel: Ni; Lead: Pb; and Zinc: Zn) on the farmland soil of this City. According to our findings, the spatial distribution of HMs in Yangchun City shows higher concentrations in the north and southeast and lower in the west and other regions. Metal content in some sampled sites of the agricultural land exceeded the soil pollution risk screening values, particularly As (7.5%), Cd (12%), Cu (4%), Hg (14.5%), and Pb (3%). Additionally, the average content of As, Cu, Cd, Pb, Hg, and Zn from the studied areas surpassed the soil background value of Guangdong Province for all metals. The absolute principal component score-multiple linear regression (APCS-MLR) was used to identify potential sources of HMs in the soil samples. There are three potential sources identified by the model: traffic emissions, natural sources, and agricultural activities, accounting for 28.16%, 16.68%, and 14.42%, respectively. Based on the ecological risk assessment, the potential ecological risk (Eri = 310.77), Nemero pollution index (PN = 2.27), and multiple possible effect concentration quality (mPECQs = 0.23) indicated that the extent of heavy metal pollution in the soil samples was moderate. Three sources were identified: traffic emissions, natural sources, and agricultural activities. We suggest that by combining the above results, a monitoring and early warning system focused on Cd and Hg can be established. The system could utilize geographic information systems and remote sensing technologies to achieve dynamic monitoring and prediction of pollution. Regular testing of soils and sustainable management practices are also recommended to control and remediate contamination.

“…It can disrupt the balance of marine ecosystems, harm the biodiversity of coastal areas, and have long-term effects on the overall health and functioning of these ecosystems . Moreover, the consumption of seafood contaminated with Hg 2+ ions can give rise to potential health hazards for certain vulnerable populations, such as pregnant women and young children. , Therefore, the development of highly sensitive and selective sensors for the convenient detection of Hg 2+ ions in coastal seawater is crucial to preserve these ecosystems and ensure the health and well-being of marine organisms and humans.…”

Despite the promising potential of carbon dots (CDs) as a photoluminescent nanomaterial in advancing spectral analysis techniques for the detection of various harmful heavy metal ions such as Hg 2+ , Cu 2+ , Cd 2+ , and Pb 2+ , the fundamental challenge of effectively eliminating the interference of transition metal ions in multi-ion systems persists. In this study, we present straightforward, efficient, and versatile manganese(II)-enhanced nitrogen and sulfur codoped carbon dots (Mn(II)-N,SCDs) specifically designed for the highly selective and sensitive detection of Hg 2+ ions. Mn(II)-N,SCDs exhibited uniform particle size (∼2.0 nm) and demonstrated excellent fluorescence performance, characterized by high fluorescence intensity and quantum yield (QY = 48.71%). The incorporation of Mn 2+ not only enhances the fluorescence characteristics but also serves to effectively block the surplus transition metal ion binding sites on the surface of carbon dots, thereby leading to a heightened selective response to Hg 2+ . Furthermore, the synthesized Mn(II)-N,SCDs also exhibited low cytotoxicity and efficient cellular uptake, enabling fluorescence imaging of living cells. Importantly, the developed fluorescence sensor exhibited a highly specific response to Hg 2+ ions even in the presence of other metal ions in phosphate-buffered solution (PBS), with a low detection limit of 0.29 nM (S/ N = 3). The efficacy of the probe was successfully demonstrated through the determination of Hg 2+ in live cells and natural coastal water samples.
