The content of atom on the surface of nanoparticle as a function of Pt nanoparticle diameter

 

 
 

 


Almost cancer cells are dead at the concentration of 10 ppm of NANOVER

 

 

 

 

    NANOVER  has strong antimicrobial efficacy against various microorganisms. The table shows the value of the minimal inhibitory concentration (MIC) of each NANOVER SCV-WA series type to inhibit the fission or multiplication of each micro-organism. The other types are presumably equal. The MIC is defined as the lowest concentration of NANOVER  that completely inhibits the growth of microoganisms.

NANOVER is not Ag ion, but metallic nanoparticles




 

          
 

 

 


NANOVER
 is not Ag ion, but metallic nanoparticles

    The binding energy of Ag core electron of NANOVER  is higer than Ag bulk (Ag foil) due to size effect of nanoparticles, which is consistent with the known research results.

    In contrast, the binding energy of Ag ion is lower than Ag bulk.


 
 

            
 

-->uniform shape and very narrow particle distribution
 

NANOVER (final nanoparticles) consists of several
smaller nanoparticles, called primary nanoparticles.

TEM image after dilution of NANOVER™  
Final nanoparticles are dissociated into several primary
nanoparticles, which appear such as satellites



 

            
 
     Good long-term stability


   


    Absorption band at approx. 400 nm appears due to surface plasmon of silver nanoparticle.
    The absorption band appears even after a year and no absorption band shows at longer wavelength (~ 700 nm) by aggregation of nanoparticles.
    good stability as a function of time
