Glucose determination, without pain and aches, is essential for biomedical applications. Minimally invasive (MI) and non-invasive (NI) are the approaches that could address these challenges. MI approaches are based on body fluids such as saliva, urine, tears, and interstitial fluid that are exploited to determine glucose levels. NI methods utilize radiation forms to determine glucose concentration without needing body fluid Read More

Aflatoxin B1 is highly toxic, mutagenic, teratogenic, and carcinogenic and is a class I carcinogen. Peanuts, cotton, and corn may be affected by AFB1 during cultivation, which can seriously jeopardize human health. Developing a simple, sensitive, and selective method for detecting AFB1 is imminent. Aptamers are obtained through in vitro screening of ligands by single-stranded oligonucleotides (DNA or RNA) through expon Read More

Background: Metformin is a biguanide derivative utilized as a first-line treatment for type 2 diabetes for people over 60 years. However, it faces certain limitations due to its incomplete absorption, resulting in a 50-60% bioavailability. In addition to its blood glucose-lowering effect, the antiproliferative effect of metformin has been demonstrated in vitro. Therefore, it is necessary to consider alternative administration ro Read More

Introduction: In this study, we optimized the extraction process, analyzed the structure and assessed the antioxidant activity of Sanghuangporus baumii polysaccharide (SBP). The present results provide important information for the Sanghuangporus baumii polysaccharides in potential natural antioxidant effects. Background: The extraction and structural analysis of polysaccharides from Sanghuangporus has gained sig Read More

Introduction: In this study, a nanocomposite film was prepared by doping silver nanoparticles onto β-cyclodextrin-chitosan functionalized Reduced Graphene Oxide (RGO), denoted as Ag/ β-CD/CS/G nanocomposite. The average diameter of the Ag NPs was found to be 62±17 nm. Methods: The fabricated composite was applied to monitor trace levels of copper ions in different industrial and environmental water samples. The mo Read More
