Abstract:

The HA nanobelts had been synthesized by using surfactants. It possesses a uniform one-dimensional nanofibers with width in 1.37nm and a BET specific surface area of 85.2m2g-1. The 31P NMR spectrum showed three –0.59ppm,-1.76ppm,-3.22ppm followed by a series of identical sidebands and one weak peak at –4.69ppm . The FTIR spectra of the nanobelts included two types of vibration; three PO4 3- stretching modes at 939.1,1030.4 and 1100.0cm-1 band were attributed to the ν1(PO4), ν3(PO4), ν3(PO4) modes respectively. Two PO4 3- bending modes at 569.6 and 608.7cm-1 bands were attributed to the ν4(PO4) modes .The bands observed around 473.9cm-1 were attributed toν2(PO4) modes. The nanobelts were novel drug carries.
