چکیده

Nanosilver was modified by aptamer (ssDNA) to obtain a resonance scattering (RS) probe (AgssDNA) for melamine (MA). Based on the catalytic effect of the probe on the Fehling particle reaction, a nanocatalytic RS assay is proposed for the determination of 0.02-1.06 μg L(-1) MA.

Utilization of triangle nanosilver to prepare spherical nanosilver and quantitatively detect trace titanium by SERS

The blue triangle nanosilver (BAgNP) sol was prepared by the two reducers of NaBH4 and H2O2. Using BAgNP as the precursor, a small spherical nanosilver (AgNP) sol in yellow was synthesized by addition of suitable amounts of X (-) (X = Cl, Br, and I). The oxidization process of BAgNP to AgNP was studied in detail by resonance Rayleigh scattering (RRS), surface-enhanced Raman scattering (SERS), l...

A label-free thrombin binding aptamer as a probe for highly sensitive and selective detection of lead(II) ions by a resonance Rayleigh scattering method.

The binding of lead(II) ions with unusually high affinity to a thrombin binding aptamer resulted in an enhancement of resonance Rayleigh scattering (RRS). A simple, sensitive, and selective assay for the direct determination of trace amounts of Pb(2+) on the basis of RRS has been proposed.

Synthesis of Pyranopyrazole Compounds Using Heterogeneous Base Catalyst Based on 1,3,5-Triazine-2,4,6-Triamine Modified Nano Rice Husk Silica

In the current study, amorphous silica nanoparticles were easily extracted from rice husk ash. The target composite was synthesized by the direct incorporation of chloropropyl groups through the condensation of nanosilica and 3-chloropropyl trimethoxysilane and then grafting of 1,3,5-triazine-2,4,6-triamine (Melamine) onto the propyl groups by the simple nucleophilic substitution reaction (RHA@...

Label-free fluorescence detection of melamine with a truncated aptamer.

The 2008 Chinese milk scandal caused by the adulteration of melamine encouraged the public to pay attention to melamine detection in milk products and other food stuffs. To allow simple and rapid detection of melamine, we previously isolated an 88 nt melamine aptamer (called Rd29C33) using the structure-switching SELEX. However, this 88 nt oligonucleotide is costly to synthesize, and may also c...

Potential Use of DNA Aptamer-Magnetic Bead Separation-PCR Assay for Salmonella Detection in Food

Background: Salmonella is one of the most common food-borne pathogens that can cause illness. In this study, the sensitivity and the specificity of Aptamer-Magnetic bead Separation-Polymerase Chain Reaction (AMS-PCR) method were determined for Salmonella spp. detection. Methods: Different concentrations of Salmonella enterica were mixed with streptavidin-magnetic beads coated with biotinylated...
