纳米技术在医学领域的研究应用

Research and Application of Nanotechnology in Medical Field

纳米是长度的度量单位,又称毫微米,即百万分之一毫米。目前,纳米技术已在多个行业得到了应用,如纳米物理学、纳米电子学、纳米生物学、纳米化学、纳米计量学和纳米加工学等。应用于药物学领域的纳米技术称为纳米药物学。纳米粒在药物学上的应用主要有纳米药物载体和纳米药物制剂2种。纳米药物的生产成本低、效率高、自动化程度高、规模大,而药物的作用也实现了器官靶向、高效和低毒等革命性的突破,并具有稳定性好、对胃肠刺激性小等优点。因此,纳米药物在国际工业领域以及医药领域均具有广阔的发展前景。阐述了纳米技术在医学领域的研究及应用。

Nanometer is a measurement unit of length, also named as millimicron （one millionth of a millimeter）. Nowadays, nanotechnology has been applied in many industries, such as nanophysics, nanoelectronics, nanobiology, nanochemistry, nanometrology, nano-machining. The nanotechnology applied in pharmacology field was named as nanopharmics. The nano-particles applied in pharmacology included nano-drug carrier and nano-medicine preparation. The nano-drugs had low production cost, high efficiency, high automation degree and large scale. And the nano-drugs realized organ targeting, high efficiency, low toxicity and other revolutionary breakthrough. The nano-drugs had advantages of good stability, small stimulation to stomach and intestines, etc. Therefore, nano-drugs had a broad development foreground in industry field and medical field in the world. The research and application of nanotechnology in medical field were reviewed.
