GQDs, quasi-zero-dimensional graphene structures, have garnered significant attention due to their remarkable physicochemical properties, including excellent photoluminescence, high surface area, and biocompatibility [1]. Meanwhile, peptides, short amino acid sequences, have proven themselves as versatile molecular entities with a crucial role in cellular targeting, signaling, and communication. The convergence of these two domains, GQDs and peptides, has opened up exciting opportunities for developing novel nanocarriers and therapeutic platforms for the effective treatment of cancer [2]. The ligation of GQDs and peptides capitalizes on the unique properties of both components. GQDs exhibit exceptional optical properties, making them suitable for imaging and sensing applications [3]. Their high surface area allows for efficient drug loading, while their biocompatibility ensures minimal cytotoxicity. On the other hand, peptides offer molecular specificity, allowing for precise targeting of cancer cells and tissues. By combining these properties, GQD-peptide nanostructures can deliver therapeutic payloads to cancer sites with remarkable accuracy [4].","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":"16 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139587861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional detection techniques like atomic absorption spectroscopy (AAS), inductively coupled plasma-optical emission spectrometry (ICP-OES) and inductively coupled plasma-mass spectrometry (ICP-MS) have limitations including high costs and insufficient sensitivity. Electrochemical sensors based on carbon nanomaterials have emerged as an attractive alternative for rapid, affordable, and ultrasensitive heavy metal analysis. Methods: This review summarizes recent advances in using carbon nanomaterials like ordered mesoporous carbon, carbon nanotubes, graphene and carbon dots for electrochemical sensing of toxic heavy metals. Synthesis methods, characterization techniques, functionalization strategies and detection mechanisms are discussed. Results: High surface area, electrical conductivity and electrocatalytic activity of carbon nanomaterials enable preconcentration of metal ions and signal amplification at electrode interfaces. This results in remarkably low detection limits down to parts per trillion levels. Functionalization with metal nanoparticles, molecularly imprinted polymers and other nanocomposites further improves sensor selectivity and sensitivity. These sensors have been applied for the quantitative detection of arsenic, mercury, lead, cadmium, chromium, and other toxic metals in lab samples Conclusion: Electrochemical sensors based on carbon nanotubes, graphene, mesoporous carbon, and carbon dots are rapidly emerging as an ultrasensitive, cost-effective alternative to conventional techniques for on-site screening of heavy metal contamination in food and environment.

The glycoproteins ferritin and transferrin, which assist in carrying iron to various body parts, are used to store iron. In terms of iron uptake, storage, and excretion, equilibrium should be preserved. Ferroptosis is an iron-dependent form of cell death with traits like lipid peroxidation buildup and ROS generation. It is distinct from other forms of cell death visually and biochemically. Many cancer cells block ferroptosis by controlling different cell survival pathways. Compared to healthy, normal cells, cancer cells are more dependent on iron. A subgroup of tumor cells known as cancer stem cells has stem-like characteristics. These are in charge of metastasis and recurrence. The liver plays a significant part in the body's detoxifying process and is the primary iron storage organ. Numerous liver disorders are frequently accompanied by excessive iron accumulation. Due to excessive iron deposits, the liver is more vulnerable to oxidative damage, which can occasionally result in liver failure. Chemotherapy, which involves administering several medications to treat cancer, may be hazardous to the body's other cells. The ferroptosis condition and high iron accumulation can potentially impair liver function. A tailored drug delivery method may ameliorate the impact of excessive iron accumulation and favorably correlate with liver damage, consequently enhancing liver function.","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":"78 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138683472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
