In new variation of ways to use nanotech to treat cancer, scientists have shown that using a scorpion toxin to target nanoparticles to brain cancer cells depletes the amount on the cancer cell surface of a protein required to make the cells invasive. From the National Cancer Institute’s Alliance for Nanotechnology in Cancer “Toxin-nanoparticle combo [...]
An international team of investigators has demonstrated in mice a nanotech method of orally delivering an anticancer therapy that would normally have to be delivered by injection.
Having demonstrated a year ago an effective nanotech method for shutting down specific gene expression in a mouse model of colitis, a team of researchers at Tel Aviv University is preparing to test this method in clinical trials for blood, pancreatic, breast and brain cancers.
The January issue of Life Extension Magazine offers a report on the eventual promise of medical nanobots.
Nanotech could make possible the controlled release within the patient of up to four different drugs by irradiation with different wavelengths of near-infrared radiation.
Research on the interactions between carbon nanotubes and neurons shows that electrical phenomena in nanotubes may lead to engineering interactions between nanomaterials and neurons.
Polishing teeth with silica nanoparticles produces much smoother surfaces than does polishing with larger silica particles, making it easier to remove harmful bacteria.
Nanowerk News reports that an international nanotech collaboration of American and Korean scientists, funded by the Korean government, has developed multifunctional gold-coated nanowires that are designed to swim through the blood stream and attach to cancerous cells via antibodies against the cancer cells. Exposure to an electromagnetic field should heat the nanowires and destroy the [...]
A new nanotech method of DNA sequencing is 30,000 times faster than current DNA sequencing methods.
Using a promising nanotech approach to deliver the RNA molecules, a type of nanoparticle described as a neutral liposome was administered to mice bearing melanoma tumors and found to cause a significant decrease in tumor growth and in the number of metastatic tumor colonies.
Previously unknown spectral properties of carbon nanotubes functionalized with DNA have been exploited to create nanotech sensors that can simultaneously detect several different substances, in real time, within living cells, to single molecule sensitivity.
The effectiveness of treatment with multifunctional nanoparticles was studied using human breast tumors grown in rats lacking an immune system so that the variation in the effectiveness of treatment could be compared among individual breast tumors.
In laboratory tests, nanoparticles that include a small molecule of nucleic acid that binds to a target molecule on prostate cancer cells were used to carry a lethal dose of the drug into the cancer cells without affecting cells lacking the cancer-specific target.
A nanotech assay for trace levels of proteins associated with cancer is a thousand fold more sensitive than are current assays.
A startup company has now received a $3.5 million grant from the state of Texas to commercialize the nanotech delivery of a drug for cancer treatment.
Nanotech membranes made of nanoporous alumina coated with diamond-like carbon films promise to minimize problems with medical implants.
A patch consisting of three layers of polymers can be loaded with nanoparticles and attached to living cells to give them nanotech backpacks.
Nanoparticles can introduce two very promising, but easily degraded, therapeutic molecules into a laboratory model of human skin, and together they are much more effective than either is alone is slowing the development of deadly melanoma skin cancer.
A noninvasive Raman microscope has allowed scientists to track carbon nanotubes injected into living mice.
