Research ArticleOpen accessEvery word in the titlePotentiometric Biosensor for Highly Toxic Pb (lead) and Cd (cadmium) Detection in Milk Using Layer-by-Layer ImmobilizationZhainagul Kakimova, Klara Zharykbasova, Aitbek Kakimov et al.Milk contamination with heavy metals such as lead (Pb) and Cadmium (Cd) poses a serious threat to public health, particularly in industrial regions. To address the need for rapid and on-site detection of these contaminants, a potentiometric biosensor was developed for the quantification of Pb²⁺ and Cd²⁺ ions in milk and dairy products. The biosensor functions by measuring the change … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 8 Feb 2026 · 1,480 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConstruction of a Glucose Biosensor by Immobilizing Glucose Oxidase within a Poly(o-phenylenediamine) Covered Screen-printed ElectrodeMiao Yuqing, Chen Jianrong, Wu XiaohuaThe glucose biosensors were prepared by the electropolymerization of the non-conductive polymer, Poly(o-phenylenediamine), onto a planar screen-printed electrode. A fabrication procedure was performed to decrease the waste of expensive enzyme. The amperometric glucose response was measured by the potensiostating of the prepared glucose biosensors at a potential of 0.3 V with ferrocene as mediator. Results show that the obtained biosensors … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,836 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiosensor Based on Xanthine Oxidase for Monitoring Hypoxanthine in Fish MeatHelena S. Nakatani, Luciane V. dos Santos, Cristiano P. Pelegrine et al.An amperometric enzyme electrode for the detection of hypoxanthine in fish meat is described. The hypoxanthine sensor was prepared from xanthine oxidase immobilized by covalent binding with glutaraldehyde and bovine serum albumin on a nafion-coated platinum disc electrode. The responses for hypoxanthine were obtained in 0.1 mol L-1 phosphate buffer (pH 7.0), at potential of 600mV vs Ag/AgCl. This biosensor … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 8,597 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Use of Biosensors to Analyse a Soldier’s Stress LevelJosé Miguel Martinho Silva, Ricardo A. Marques Lameirinhas et al.Currently and increasingly, biosensors are present in our daily lives, even if tendentiously and imperceptibly. As such and given their importance, the scientific community is clearly interested in making progress in this research field. This study is part of the study of biosensors using pre-gelled electrodes and was focused on the analysis of the ability to extract information on the … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 1 Mar 2024 · 4,972 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHydrogen Peroxide Biosensor Based on the Direct Electrochemistry of Myoglobin Immobilized in Poly-3-Hydroxybutyrate FilmXiang Ma, Rongwu Yang, Genxi LiDirect electrochemistry of myoglobin (Mb) was observed in a stable film composed of a natural lipid polymer (poly-3-hydroxybutyrate) and Mb, the film of which was modified on a pyrolytic graphite electrode. The apparent formal potential of Mb was at about -260 mV in an acetate buffer solution with pH 5.0. Moreover, Mb in the polymer film exhibited catalytic activity towards … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,872 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical and Biological Warfare: Should Rapid Detection Techniques Be Researched To Dissuade Usage? A ReviewMark R. Hurst, Ebtisam WilkinsChemistry, microbiology and genetic engineering have opened new doorways for the human race to propel itself to a better future. However, there is a darker side to Bioengineering. One element of this is the manufacture and proliferation of biological and chemical weapons. It is clearly in the interest of humankind to prevent the future use of such weapons of mass … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Monitoring of Endocrine-Disrupting Chemicals: Analytical Chemistry and Biological Assessment ApproachesChangjin Li, Jing Huo, Zijun Dou et al.Endocrine-Disrupting Chemicals (EDCs) in aquatic environments pose significant threats to ecosystems and human health. These compounds interfere with hormonal regulation at low concentrations and have non-monotonic dose-response relationships, posing challenges to conventional risk assessment. This review systematically compares current EDC monitoring methods, including instrumental chemical analysis and receptor-based biological detection systems, to evaluate sensitivity thresholds, sample throughput, and mechanistic selectivity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 3 Jul 2026 · 1,081 accessesView PDFCite

Review ArticleOpen accessIn the abstractSelf-Assembly Peptides-a ReviewOlushola Sunday Ayanda, Olusola Solomon Amodu, Cyprian Yameso Abasi et al.Self-assembling of peptides is a spontaneous process by which peptides are self-organized to form well-ordered structures by intramolecular and intermolecular interactions.This process is controlled by the balance of the forces (attractive andrepulsive) within the peptide molecules. Notable methods used for the synthesis of self-assembly peptides are solid-phase synthesis, liquid-phase synthesis,recombinant technology, and the use of external fields. The self-assembled nanostructure-based … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 12 Aug 2022 · 5,739 accessesView PDFCite
