Nano Diamond Powders for Drug Delivery Applications
Diamond is the
hardest substance in the world. Mention it, people often associate it with
super hard materials, jewelry and industrial diamond drill bits, grinding
wheel. But scientists used the characteristics of nano diamond to delivery successful
treat leukemia drug to the pathological cells for malignant tumor treatment.
the new
scientific research using nano diamond powders technology has solved the
difficult that the tumor cells to discharge the treatment drug to cells in
vitro, especially in the process of chemotherapy, the diseased cells resistant,
this has been a difficult for the doctors. The research is
published in Nanomedicine: Nanotechnology, Biology.
Problem: leukemia
cells drug resistance
Daunorubicin is a
common drug for leukemia treatment, which treat the illness by slowing down and
prevent the growth and proliferation of tumor cell, and eventually kill the
diseased cells. But in the process of treatment pathological tumor cells is
easy to produce resistance phenomenon to daunorubicin.
Nano diamond
intervention therapy
At present, the
way that the medical community solve drug resistanc is to develop antibody, but
more clinical trials show drug toxicity is big and the effect is not obvious.
In view of this,
NUS and UCLA researchers have begun to break through the train of thought, to
treat particle size only 2 ~ 8 nm nano diamond powders.
Researchers fix
soft erythromycin on the surface of nano diamond, and then put the mixture to
diseased cells. The results showed that the nano diamond would be able to bring
soft erythromycin into cells and cells haven't been discharged as before, so as
to solve the problems of the diseased cells resistance. Because of nanometer
size diamond non-invasive and unique surface features, diamond particles can
easily be released into the blood vessels and not causing blocked blood vessels
at the same time.
Dr Chow said:
"the intervention of nanodiamond greatly improve the possibility of
biological adaptability and tolerance combining, and to enhance curative
effect. at present, in vivo and in vitro drug safety test results show that the
drug with medicinal properties is better, this laid a good foundation for
further.
Professor DeanHo
added: nano diamond is a very promising treatment carrier on medical research. At
present, we will further determine which drugs can be hold by nanometer diamond
for specific disease treatment, so as to maximize implement the welfare to
patients.
