Colorimetric Aptasensor Using Unmodified Gold Nanoparticles for Homogeneous Multiplex Detection
Colorimetric aptasensors using unmodified gold nanoparticles (AuNPs) have attracted much attention because of their low cost, simplicity, and practicality, and they have been developed for various targets in the past several years. However, previous research has focused on developing single-target assays. Here, we report the development of a homogeneous multiplex aptasensor by using more than o...
متن کاملA gold nanoparticle-based label free colorimetric aptasensor for adenosine deaminase detection and inhibition assay.
A novel strategy for the fabrication of a colorimetric aptasensor using label free gold nanoparticles (AuNPs) is proposed in this work, and the strategy has been employed for the assay of adenosine deaminase (ADA) activity. The aptasensor consists of adenosine (AD) aptamer, AD and AuNPs. The design of the biosensor takes advantage of the special optical properties of AuNPs and the interaction b...
متن کاملSimple, rapid and label-free colorimetric assay for Zn2+ based on unmodified gold nanoparticles and specific Zn2+ binding peptide.
A simple strategy based on unmodified AuNPs and specific Zn(2+) binding peptide is exploited here as a new label-free mechanism for the rapid colorimetric Zn(2+) assay.
متن کاملA G-quadruplex-based Label-free Fluorometric Aptasensor for Adenosine Triphosphate Detection.
A G-quadruplex-based, label-free fluorescence assay was demonstrated for the detection of adenosine triphosphate (ATP). A double-stranded DNA (dsDNA), hybridized by ATP-aptamer and its complementary sequence, was employed as a substrate for ATP binding. SYBR Green I (SG I) was a fluorescent probe and exonuclease III (Exo III) was a nuclease to digest the dsDNA. Consequently, in the absence of A...
متن کاملSimple, 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...
