چکیده

Cytidine triphosphate (CTP) stabilized-Au nanoparticles (CTP-AuNPs) allow a quantitative assay of Ca(2+) down to a concentration of 10(-4) M with high selectivity towards Ca(2+) ions over various metal ions including Mg(2+) and the detection range of this probe also can be easily tuned by changing the concentration of CTP.

Simple, Fast and Selective Detection of Adenosine Triphosphate at Physiological pH Using Unmodified Gold Nanoparticles as Colorimetric Probes and Metal Ions as Cross-Linkers

We report a simple, fast and selective colorimetric assay of adenosine triphosphate (ATP) using unmodified gold nanoparticles (AuNPs) as probes and metal ions as cross-linkers. ATP can be assembled onto the surface of AuNPs through interaction between the electron-rich nitrogen atoms and the electron-deficient surface of AuNPs. Accordingly, Cu2+ ions induce a change in the color and UV/Vis abso...

Comparing signal amplification of thiocyanated Gold nanoparticles in the presence of different ions

Detecting is the most important section in all kinds of sensors. In this regard, the amplification of surface plasmon resonance intensity of gold colloids nanoparticles (GNPs) was studied in the presence of several ions. GNPs were synthesized and then capped by thiocyanate and characterized via DLS and TEM image. In the next step the effect of different concentrations of ions such as iron, copp...
