functionalized gold nanoparticles are one of the most studied materials due to their very high physical and chemical properties. There are many ways today to synthesize gold nanoparticles, especially the two widely used and common classic methods. For example, in the first method, gold nanoparticles are prepared by reducing HAuCL4 with sodium citrate in boiling water.
What are gold nanoparticles used for?
Gold nanoparticles used for:
Electronic Optical Properties These gold nanoparticles are widely used and are used for electronic conductors and sensors.
The insulating and thermal properties of gold nanoparticles are used in the preparation of a type of chip that is very popular in the electronics industry.
Among the uses of gold nanoparticles in the medical field are drug delivery, cancer treatment (gold nanoparticles cancer), and diagnostic imaging. The unique chemical and physical properties of gold nanoparticles make these compounds suitable for pharmaceutical applications. Gold nanoparticles are stable and non-toxic, so they do not damage healthy tissue. The functional groups can be easily applied to the surface of gold nanoparticles using a thiol-based covalent bond.
Why are gold nanoparticles red?
Multiple states occur when a light beam collides with a specific wavelength:
Depending on the wavelength of the light emitted, it can also determine the color of the light, and the size and size of the fragment will vary, such as the amount of absorption, reflection, and so the fragment can be seen in red.
Because smaller particles absorb shorter wavelengths (blue and violet …), so we see the light passing through, which is longer wavelengths (reds) and they are seen in bright reds. Surface electrons are gold atoms with electric light fields.
Functionalized Gold Nanoparticles and Their Biomedical Uses
Functionalized Gold Nanoparticles and Their Biomedical Uses and advantages of gold nanoparticles :
Gold nanoparticles are excellent drug carriers and can play a key role in photodynamic, cancer and photothermal treatment. Due to the intrinsic physical properties of gold nanoparticles for biological applications, these nanoparticles are expected to be a vital component of treatment for humans.
Nanoparticles can play a key role in photodynamic, cancer and photothermal treatment. Due to the unique and intrinsic properties of gold nanoparticles for biological applications, these nanoparticles are recognized as an essential element in human therapy.
In general, gold nanoparticles articles, the versatility of gold nanoparticles, and other unique properties of gold allow researchers to conduct extensive research for therapeutic purposes.
Gold nanoparticles are one of the most used products for the diagnosis, treatment and treatment of cancer. Benefits of these particles for use in cancer treatment include high biodegradability, non-toxicity, and non-selective accumulation in cancer cells.
Many studies and experiments have shown that these particles are used as a countermeasure enhancer, as a heat treatment agent, for X-ray and Raman imaging, and for enhancing tumor radiosensitivity.
The ability to transfer the drug to the patient’s target tissue is a medical crisis because targeted drug delivery improves the effectiveness of treatment by increasing drug accumulation in the target tissue and reducing the side effects of reducing drug congestion in healthy tissue. Fortunately, the unique properties and non-toxicity of this metal have made it a drug carrier.
