This review provides a comprehensive examination of the application of fluorescence materials for the detection of latent fingerprints in forensic sciences. Traditional methods like powder dusting, cyanoacrylate fuming, chemical methods, and small particle reagent techniques have shown limitations due to issues like low contrast, sensitivity, selectivity, and high toxicity. To overcome these drawbacks, recent focus has shifte Read More

Background: In this work, the reduced graphene oxide decorated with gold nanoparticles (Au/rGO) had been synthesized on glass carbon electrode (GCE) using a simple one-step electrochemical method. The molecularly imprinted poly(p-aminobenzoic acid) (PABA) film was prepared for the analysis of sunset yellow (SY) on Au/rGO/GCE by electropolymerization of p-aminobenzoic acid (pABA) and SY.Methods: Methods, such as Read More

Background: Single nucleotide polymorphisms (SNPs) are important hallmarks in various pathological activities, especially genetic and inherited diseases, and detecting them with accuracy, high throughput and low cost becomes increasingly necessary.Methods: Herein, we have developed a new label-free and sensitive detection method for SNPs assay. Due to its favorable traits, the method presents an excellent performanc Read More

Aims: The main goal of this research was to find a simple, selective, sensitive and rapid protocol for the detection of traces of levofloxacin (Lev) in seawater, pills, urine, and human plasma samples by using a novel sorbent made of molecularly imprinted polymer (MIP) for its pipette-tip micro-solid phase extraction (PT-μSPE), followed by spectrophotometry. Parameters affecting the method were evaluated employing one-varia Read More

Background: It has become increasingly important to use non-toxic nanomaterials for treating industrial wastewater that contains organic dyes, such as methyl green.Method: A sol-gel method was used to synthesize aluminum oxide nanoparticles from waste aluminum and investigate the physicochemical process involved in their removal from methyl green.Result: The synthesized adsorbent was characterized using EDX, U Read More

Introduction: More than sixteen countries are infected with the highly pathogenic avian influenza A-H5N1 virus. As the virus circles the world, it has led to the slaughter of millions of poultry birds as well as the infection of farmed mink in Europe and among seals and grizzly bears on the Northern coast of America; some infected mammals exhibited neurological symptoms like disorientation and blindness, which marks the first larg Read More
