What is a nanoparticles?
its is a nanoparticle of gold
What does gold do in injected into your body?
Gold nanoparticles can be injected into people to check for tumors
How transgenesis can be done using nanoparticles?
Donor DNA is coated on to gold nanoparticles andaccelerated at high speed toward a culture of recipient cells (ballistic method of gene transfer). Some cells will be transformed. These transformed cells are grown further. They are transgenic in nature since a foreign gene was inserted into the genome by the method described above
What is the difference between gold colloids and gold nanoparticles?
Gold colloids have multiple definitions. They have been used for many years as a dietary supplement (see http://www.purestcolloids.com). Gold colloids provide the body with minerals to maintain optimum health. They have been used for many years as a therapeutic for arthritis. They have also been used in lateral flow applications such as in pregnancy tests (see http://www.bbigold.com). Gold nanoparticles, on the other hand, must possess properties that are specific for nanotechnology applications. Sample nanotechnology applications include Resonance Light Scattering (RLS), Surface Enhanced Raman (SERS), in-vivo photothermal cancer therapy, imaging, and diagnostics. These applications demand monodispersity in size and shape with highly reactive surfaces because these applications depend on the quality of the individual nanoparticles, not just the properties of the nanoparticles in bulk. This is the definition of nanotechnology. In order to make gold nanoparticles suitable for these applications, the gold nanoparticles must have the following characteristics: 1. Provide rod shapes for in vivo applications. 2. Spherical gold nanoparticles that are not manufactured using thiol or citrate chemistry which result in unreactive, polydisperse gold nanoparticles. 3. Conjugations that are based on solid, covalent bonds, not adsorption which can results in lost conjugations. For gold nanoparticles see Nanopartz at http://www.nanopartz.com.
How are nanoparticles manufactured?
on a small scale in the lab there are many different ways. Most scientists have to do a search in existing litrature to find a way of making nanoparticles similar to what they want and then conduct systamatic experiments from there to see how changing paramaters will change the size and shape of the particles, with the goal of developing their own synthesis. Two common reactions you will hear of to make nanoparticles are the Stober reaction, which uses tetraethylortho silicate, ammonium hydroxide, water and differing alcohols to make silica particles, these particles are used to make artificial opals, which in turn are used to study properties of light and its interaction of matter. Another common one is the Lee and Miesel method of making silver or gold nanoparticles, this makes use of a metal salt and a solution of sodium citrate to reduce the salt to pure metal.
What is aggregation of nanoparticles?
Aggrgation of nanoparticles is where they stick together. This is undesirable in nanoparticle solutions, we want each nanoparticle to remain seperate. To combat this differing amounts of salts can be added to stop agglomeration, sodium citrate is one that is used for silver and gold nanoparticles. The zeta potential of the nanoparticle is a masure of its overall charge, ideally we want nanoparticles with a high positive or negative zeta potential as like charges repel each other and will stop nanoparticles from agglomerating.
Does gold affect fertility in man?
Yes it is. According to few studies mixing gold nanoparticles with fresh sperm samples decreased sperm motility by 25%, and caused some sperm fragmentation.

How do you make fifo method in tally?
how to fifo method in tally 9 gold
Is gold mining open-pit or underground?
Gold can be mined by either method.
What is the method for gold panning?
Gravity separating.
What is gold coating?
Gold coating is a method of depositing a thin layer of gold onto the surface of another metal.
