Research ArticleOpen accessIn the keywordsPotentiometric 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 PDF Cite

Research ArticleOpen accessIn the keywordsAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,081 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPreparation and Properties Study of PCM@ECD BilayerYan Zhao, Heng Zhang, Yanfei Zhao et al.This study reports the fabrication of a core-shell active bilayer membrane (PCM@ECD) via a combined tape-casting and layer-transfer methodology. The inner core layer comprised Pectin-Chitosan (PC) microcapsules, synthesized by complex coacervation, encapsulating Orange Peel Essential Oil (OPEOM) with an embedding efficiency of 83.08%. The outer shell layer consisted of Ethyl Cellulose (EC) doped with zinc-doped carbon dots (Zn-CDs, average size: … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 8 May 2026 · 1,600 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Immunity of Hybrid Grouper (Epinephelus sp.) Against Viral Nervous Necrosis Using a Recombinant Protein Nanovaccine from Chlorella VulgarisUun Yanuhar, Herly Evanuarini, Heru Suryanto et al.Hybrid Grouper (Epinephelus sp.) is an important export commodity in marine aquaculture, yet Viral Nervous Necrosis (VNN) remains a major threat. Nanovaccines are a type of vaccine developed by combining vaccine ingredients with silver nanoparticles and recombinant protein from Chlorella vulgaris. These formulations are designed to effectively boost the body's immune system response to prevent disease infection and destroy pathogenic … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 22 Nov 2025 · 2,154 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Degrading Calcium Phosphate on the Remodelling and Mineralisation of Avascular Osseous Tissue in a Rat Calvaria ModelTulio Fernandez, Carlos H. Valencia, Yuann Li et al.Artificial bone graftingis the subject of intensive investigation for craniofacial reconstruction. Among the syntheticcandi date materials, those incorporating Calcium Phosphates (CaP) have gained popularity, due to their osteoinductive properties. Despite many quantitative studies on the degradation rates of CaP biomaterials in vitro, there is lack of quantitative studies in relation to bone remodelling kinetics in vivo. In this investigation, we … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 24 Dec 2014 · 7,208 accessesView PDF Cite
