How are gold nanoparticles made?

How are gold nanoparticles made?here is gold nanoparticles introduction,Nanoparticles are so-called fine particles of material that are made by physical, chemical or biological methods of the primary material, for example gold and silver nanoparticles are fine particles of gold and silver due to differences in size and proportion. Their mass by volume has very different properties. Silver and gold nanoparticles are produced in sizes from about 1_1000 nanometers and are used in the pharmaceutical, glass, medical and many other industries.

  • One of the important properties of nanoparticles is the high surface-to-volume ratio of these materials, which can be used to produce powerful catalysts at the nanoscale.
  • Recently, nanocomposites have been used in the manufacture of sunscreens, new and highly resistant paints and coatings for glass, glasses, tiles and ceramic coatings.
  • Many powder and spray nanoparticle products are currently used in various parts of automobiles, sunglasses, anti-glare, anti-varnish fabrics and solar panels.
  • Studies show that particles of less than one micron with low solubility rapidly penetrate the lung cells and cause more toxicity. The effects of aerosols on nanoparticles are very small and depend on the size of the particle and the duration of exposure, when the materials are converted to nanoscale changes in their chemical, biological, and catalytic properties.
  • Large companies producing antifungal and viral pharmaceuticals, glass factories, and medical device manufacturing plants in each country are major buyers of these nanoparticles. They are either producers of nanoparticles or import these products from other countries where they are produced.

What are gold nanoparticles used for?

What are gold nanoparticles used for?gold nanoparticles synthesis  are also synthesized in two ways, and these gold nanoparticles are highly active in chemical reactions. Gold nanoparticles are also used in medicine and pharmacy. They are cellulosic; they are generally better suited for the disinfecting properties of silver nanoparticles, but in other industries the superior nanoparticles cannot be identified because they each have different applications.

Are gold nanoparticles toxic?

Are gold nanoparticles toxic?Materials that are safe in the bulk state when they are converted to the nano state can be toxic and dangerous; in addition, the small size of the nanoparticles enables them to overcome the body’s barriers.

Another cause for concern about exposure to nanoparticles is that the nanoparticles are able to bind to or react to other hazardous pollutants in water or air, thus facilitating their transmission to the body. In assessing the risks of exposure to nanoparticles such as their size and distribution, shape, properties, surface charge, mass, concentration and distribution are important.

These nanoparticles are not completely safe for human health and other organisms. Due to the rapid absorption of nanoparticles through the skin, respiration and mucous membrane cells and then distribution to the target tissues, the nanoparticles impair the function of different parts of the body.

The relationship between particle size can affect the biological properties and different ways of exposure. The decrease in particle size causes a sudden increase in absorption or toxicity. These effects are small at first but become irreversible as the nanoparticles continue to enter the body. In addition, new and unknown toxicities may occur due to the new material.

Gold Nanoparticles in Biology and Medicine

Gold Nanoparticles in Biology and MedicineThe biological importance of gold nanoparticles among other nanoparticles has led to increased use of these nanoparticles in medicine, creating the need for a safe and safe method of synthesis, while green chemistry has provided a low-cost, effective, and non-toxic method of synthesis.

In recent years, the use of plant extracts for the preparation of metallic nanoparticles has been suggested as an easy, affordable and safe alternative to chemical and physical methods, an emerging and green chemistry approach.

There are many plants with diverse properties for the synthesis of nanoparticles that have not yet been identified and used. One of the herbs that has medicinal, antibacterial, and anti-ulcer properties is Thyme, which the Research Center has used as a reducing agent for the synthesis of gold nanoparticles. In addition to being safe, this method of synthesis is very fast and inexpensive, with no toxicity in the synthesized nanoparticles, and provides antimicrobial and anti-ulcer properties.
