Radial Flow Assay Using Gold Nanoparticles and Rolling
With the aim to prepare fluorescent magnetic nanoparticles (MNPs) for metal ion detection, the surface of carboxylated MNPs was coated with rhodamine hydrazine (RhH) by using dicyclohexylcarbodiimide (DCC)/4-dimethylaminopyridine (DMAP) as... metal nanoparticles has led to the development of a number of assays for a variety of target species. but were unable to detect lower concentrations of Cu2+ ions.We therefore conclude that the minimum concentration of Cu2+ detectable by eye is approximately 50 mm.This lowest detectable concentration cannot be compared with that obtained with the help of advanced instruments, but we believe

Detecting lead in water with nanoparticles
The tiny hairs on the "nano-velcro" particles trap heavy metal ions in their grasp allowing the level of pollution to be calculated with a voltage-measuring device (Image: Northwestern University) how to delete words ive used on keypad Gold nanoparticles (AuNPs) are the most widely studied nanomaterial because of their unique optical, chemical, electrical, and catalytic properties and have attracted much interest regarding the applications to detection of toxic metal ions. In this paper, we propose a technique for detection of divalent mercury using AuNPs and Mercury-specific-oligonucleotide–conjugated resonators (MSOIRs. How to ask questions on blogger

Polymer like chitosan is being used with gold nanoparticles to detect copper and zinc ions and detection till very low concentrations of the toxic metal ions is obtained. Keywords: Surface Plasmon Resonance, Optical sensor, metal nanoparticles, reducing agent,chelating agent, polymer capping.

  • In this work, we report sensing of Zn2+ ions using chitosan capped colloidal gold nanoparticles in aqueous media. The chitosan capping not just acted as an electro-static stabilizer to the colloidal gold nanoparticles, but also could bind to Zn2+
  • gelatin and silver nanoparticles for the detection of metal ions. The aspects of chemical synthesis of silver nanoparticles studied in this research are the use of microwave heating techniques, the use of glucose as reducing agent, and the use of gelatin and tween-20 as stabilizers. Optimum experimental conditions were used to study the stability and performance of silver nanoparticles
  • which gold nanoparticles can strongly catalyze the reduction of silver ions to silver metal with hydroquinone. Therefore, each gold nanoparticle anchored on the DNA
  • binary metal oxide nanoparticles not only act as spacers to reduce the restacking of individual graphene sheets but also behave as an electrochemical catalyst, which enhances the sensing performance. Our results suggest that the RGO/NiWO 4 nanocomposite can indeed be used as an effective electro-catalyst for the simultaneous detection of toxic heavy metal ions. Not limited to testing in water
