NANO METALS AND METAL DERIVATIVES

Antimony (III) oxide nanopowder (Sb203) [1309-64-4] M 291.5, bulk density 0.5-0.6g/ml. It is available in particle size of 250nm (BET). It is nsed in paints, pigments, enamels, glasses and flame-proofing canvas. It is toxic and should not be inhaled. 

Antimony-tin oxide nanopowder [ATO, (Sn02)o.9(Sb205)o.i] M 167.0. It is available in particle size of 50mn and has the alloy composition of 89-93% tin(IV) oxide and 7-11% antimony(V) pentoxide. The surface area is 74 mVg. It is toxic and should not be inhaled. 

Cobalt nanoparticles (surface modified with L-cysteine ethyl ester) ethanol wet are available as 10nm black powder (wet with EtOH) which is best used within 3 months. The material can be easily transferred into stable aqueous suspensions, and can be used as a starting material for surface modifications (e.g. dextran coating) or the preparation of magnetic polymer microspheres. 

Copper zinc iron oxide, 98.5% trace metal basis (zinc copper ferrite, copper zinc ferrite) [66402-68-4] M 416.3 (CuZnFe404), d 4 5.5. It is a nano powder with particle size 100nm (BET). The actual particle size is 50mn (XRD) and is cormnercially available. 

Gold nanoparticles stabilised by agarose (A-AuNP). K.V. Katti and coworkers [Kattumirri et al. Appl Phys Lett 88 153114 2006] prepared this similarly, but replacing GA by agarose. A-AuNPs were rrsed for sirrface-enhanced Raman spectroscopic detection of DNA nucleosides as well as the other apphcatiorts stated above.
