India has more than30 industries and50 institutes engaged in nanotech research and development , with most efforts focusing on chip design , nanomedicine and nanomaterials .
“ Manpower and animal models are not always available , and where available , the expertise specific for nanomedicine is scarce ,” Swai told SciDev.Net .
As the least circulatory unit , microcirculation affects the delivery and metabolism of drugs greatly , and has become the important responsive stage of nanomedicine research .
微循环作为机体最小的循环单位,极大地影响纳米药物的运输、代谢,成为纳米医学研究的重要平台;
Conclusion As a novel method of preparing nanomedicine , supercritical fluid is highly efficient , energy saving and environmentally acceptable , and it is promising for the further application .
At present , many technologies have been used for preparing nanomedicine , such as , emulsion , microemulsion , ultrasonic solvent-nonsolvent , spay drying and high-pressure homogenization , and so on .
The details are given as follows . Chapter1 : IntroductionThe research of nanomedicine has attracted wide attention in recent years . And the research of polymer nano-drug provides a theoretical basis and practical guidance on the prevention and treatment of cancer .
These features provide a new platform for biomedical applications including enhanced medical imaging , targeted drug delivery , immunoassay detection , etc. The combination of the unique structural characteristics and multifunctional properties of magnetic nanoparticles will bring new opportunities in the field of nanomedicine .
CONCLUSION : The application of nanomedicine carrier and nanotechnology not only sheds a new light on the traditional drugs whose applications are strongly restricted by their poor solubility , high toxicity and poor stability , but also enhances their therapeutic efficiency with lower dosage through targeting effect .
Chapter 1 begins with a summary on dendrimer history , structure , synthesis , physico-chemical properties , and applications in different fields . The definition of drug delivery systems and nanomedicine is introduced . On the basis of the summary , the importance of the development of dendrimer-based drug delivery systems is given.Chapter 2 systematically introduces the effect of poly ( amidoamine ) ( PAMAM ) dendrimers on the solubility , in vitro release rate , pharmacodynamic behaviors of drugs .
