These unique capabilities unlock diverse applications in disease diagnosis, electrochromic glass, solar energy, radiation shielding, and wearable devices.

Performance & Application

Metal Xano generates pure metal and metal oxides nanoparticles with the particle size distribution ranging from 1 nm to 100 nm. It can also produce metal nanosheets or nanorods. Metal nanomaterials have created an influential impact in the applications of semiconductor and biomedical sciences, such as electronic devices, photocatalysis, solar cells, cosmetics, targeted drug delivery and wound healing, to name but a few.


Pure gold nanoparticles for optimised thin film resistivity


TEM images show that gold particles generated in de-ionised water are about 5 nm in diameter, with the lattice spacing of 0.25 nm, corresponding to the (1 1 1) plane of gold.


The characteristic peaks in the XRD identify the particles as pure gold unoxidised.  The Scherrer equation shows crystallite sizes of 6.3 nm in (1 1 1) plane and 4.3 nm in (2 0 0) plane.  The mean size is 5.3 nm.


Statistics from TEM images show a gold particle size distribution from 4 to 10 nm, with an average diameter of 6.3 nm, conforming to the results from XRD analysis.

The characteristic peaks in the XRD are identical to those of cubic Cu and CuO.



Methods for producing nanomaterials

Solution-based methods

Spray pyrolysis, sol-gel dip, spin coating, etc.

The solution-based methods usually involve toxic precursors, complex synthesis steps in preparation, followed by hours of post treatments. In terms of mass production, some of the methods, such as electrodeposition or hydrothermal synthesis, would also leave behind a large amount of harmful waste.

Vapour-based methods

Thermal evaporation, radio-frequency sputtering, electron-beam evaporation, etc.

The vapour-based methods require expensive equipments. In terms of mass production, the size of the produced thin films is limited by the dimensions of the vacuum chamber.



Nanovie's electro-explosion & spray coating technology

Cost effective, environment friendly and a much larger film size.
