In photothermal cancer therapy, many gold nanoparticle molecules are used in each test and they must all be uniform in size. Including PEG coating, the nanoparticles measured to be ~130 nm in diameter. [1] Gold nanoparticles that act as drug delivery systems in conjugation with chemotherapeutic drugs typically range in size from 10 to 100 nm. [2]
Photothermal therapy: Certain nanoparticles, like gold nanoparticles or carbon nanotubes, can absorb light and convert it into heat. This property is harnessed for photothermal therapy, where these particles are targeted to cancer cells and then heated with laser light, causing localized cell damage and cell death .
Heat treatment involves using radio waves to heat up tiny metals that are implanted in cancerous tissue. Gold nanoparticles or carbon nanotubes are the most likely candidate. Promising preclinical trials have been conducted, [32] [33] although clinical trials may not be held for another few years. [34]
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
Gold nanoshells, coated silica nanoparticles with a thin layer of gold. [6] have been conjugated to antibodies (anti-HER2 or anti-IgG) via PEG linkers. After incubation of SKBr3 cancer cells with the gold nanoshells, an 820 nm laser was used to irradiate the cells. Only the cells incubated with the gold nanoshells conjugated with the specific ...
Kanzius RF Therapy is an experimental cancer therapy that employs a combination of either gold or carbon nanoparticles and radio waves. [2] [8] [9]The specific absorption rate for radio waves by living tissue in the proposed wavelengths and intensity levels is very low.
