Thermochromism refers to the phenomenon where a material undergoes color changes under temperature changes. This change is usually caused by changes in the electronic or molecular structure of the material. Its application principle mainly involves t...

Gold Nanoparticles for Screen Printed Electrode

  • December 26,2018.

    Screen printed electrode is a new type of sensor. After the gold nanoparticles were deposited by electrochemical reduction and modified with ionic liquid, polyaniline nanotubes and chitosan at the screen-printed electrode, the reaction of hydrogen peroxide and phthalic diamine catalyzed by HRP was used as the amplification method to generate a more sensitive response in DNA detection.


    For example, ethanol biosensor based on nano-gold modified screen-printed electrode is to fix ethanol dehydrogenase on the screen-printed electrode by adsorption method and modify it with nano-gold, which greatly improves the current corresponding to the electrode and provides the sensitivity of the sensor.

    The optical-electronics properties of gold nanoparticles are being explored widely for use in high technology applications such as sensors probes, electronic-conductors, therapeutic agents, drug delivery in biological, medical applications and catalysis.


Gold Nanoparticles for Screen Printed Electrode


    Gold Screen Printed Electrodes have already been used in a number of analytical studies devoted to metal species, including their determination in various practical samples, or in the configurations of various sensors / biosensors for detection of biologically active compounds.

    HOWU is supplying gold nanoparticles of different particle sizes. The dispersion solution is also available. It can be carried out according to the requirements of customers at different concentrations and solvents.

    We pay special attention to the quality assurance of the products and services we deliver. We believe that this is the best way to make products work as effectively as possible. 

    We can ship gold nanoparticles powder and diserpsion all over the world via Fedexs, DHL, TNT,etc.
