Nanoparticulate Drug Delivery Systems (Drugs and the Pharmaceutical Sciences)

Nanoparticulate Drug Delivery Systems (Drugs and the Pharmaceutical Sciences)



By Deepak Thassu, Michel Deleers, Yashwant Pathak
Publisher:   Informa Healthcare
Number Of Pages:   376
Publication Date:   2007-03-30
ISBN-10 / ASIN:   0849390737
ISBN-13 / EAN:   9780849390739
Binding:   Hardcover
Product Description:
Since the advent of analytical techniques and capabilities to measure particle sizes in nanometer ranges, there has been tremendous interest in the use of nanoparticles for more efficient methods of drug delivery. This expertly written guide addresses the scientific methodologies, formulation, processing, applications, recent trends, and emerging technologies in the research of nanoparticulate drug delivery systems (NPDDS). It extensively covers applications of NPDDS, including lipid nanoparticles for dermal applications, nanocarriers for the treatment of restenosis, ocular, central nervous system, and gastrointestinal applications, and use as an adjuvant for vaccine development.

谢谢arqiu博士,辛苦了。

请教arqiu博士一个问题:我制备高分子微球是,采取的是用注射器把高分子混合液滴加到含有交联剂的液体中,但得到的“微球”(不是完全是球状的),其与烧杯接触的面是平的,就是的不懂球形的微球,请问为什么呀?怎么解决?谢谢!

形状是各种作用的综合结果。微球的成形受到的主要影响因素有:注射针头的半径形状、高分子混合液的表面张力、交联剂的交联反应速度、及交联剂溶液的表面张力、粘度等理化性质的影响。因提供的实验信息有限,很难说出具体的原因,但你可以尝试改变上述因素看看。

另外,对于采取用滴液的方式制备微球,可以考虑在针头和交联剂溶液之间加一电场,增加静电力对液滴的作用,一方面可以影响到微球的形貌,另一方面还可以提高制备速度。国内外这方面的研究较多的是 海藻酸钠溶液 滴加到 CaCl2溶液中制备微囊,你可以借鉴一下。大连化物所的马小军在这方面有不少论文,可参阅。
