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.
What is the difference between nanoparticles and nanotechnology?
nanoparticles are basicly microscopic particles. Nanotechnology is the technology used to manipulate these nonoparticles for human use.
Are nanoparticles the same as ordanary particles?
no they are not. nanoparticles are much smaller than normal/ordinary particles
Where can you find nanoparticles?

Nanotechnology and its importance in Medical Sciences?
Nanotechnology is the manipulation of matter on an atomic and molecular scale. It has the potential to revolutionize many fields, including medicine. Importance of nanotechnology in medical sciences Nanotechnology has the potential to improve the diagnosis, treatment, and prevention of diseases in a number of ways. For example, nanoparticles can be used to: Deliver drugs more effectively. Nanoparticles can be engineered to target specific cells or tissues, which can reduce the side effects of drugs and improve their efficacy. For example, nanoparticles are being used to develop new treatments for cancer and other diseases. Improve imaging techniques. Nanoparticles can be used to create contrast agents that can improve the resolution and sensitivity of medical imaging techniques such as MRI and CT scans. This can help doctors to diagnose diseases earlier and more accurately. Develop new diagnostic tools. Nanoparticles can be used to develop new diagnostic tools that can detect diseases at an earlier stage. For example, nanoparticles are being developed to detect cancer cells in the bloodstream. Create new tissue engineering scaffolds. Nanoparticles can be used to create new scaffolds that can help to repair or regenerate damaged tissues. For example, nanoparticle-based scaffolds are being used to develop new treatments for spinal cord injuries and other conditions. Examples of nanotechnology applications in medical sciences Here are some specific examples of how nanotechnology is being used in medical sciences today: Nanoparticles are being used to deliver chemotherapy drugs to cancer cells. This can help to reduce the side effects of chemotherapy and improve its effectiveness. Nanoparticles are being used to create contrast agents for MRI scans. This can help doctors to diagnose cancer and other diseases earlier and more accurately. Nanoparticles are being developed to detect cancer cells in the bloodstream. This could lead to earlier diagnosis and treatment of cancer. Nanoparticle-based scaffolds are being used to develop new treatments for spinal cord injuries. These scaffolds can help to promote nerve regeneration and improve function. Nanoparticles are being used to develop new vaccines. Nanoparticles can help to deliver vaccines more effectively and improve their immune response. Future of nanotechnology in medical sciences Nanotechnology is still in its early stages of development, but it has the potential to revolutionize many aspects of medicine. In the future, we can expect to see nanotechnology used to develop new and more effective treatments for a wide range of diseases. Nanotechnology could also be used to develop new diagnostic tools and imaging techniques that can help doctors to diagnose diseases earlier and more accurately. Overall, nanotechnology has the potential to make a significant impact on human health and well-being.
What is the effect of silver nanoparticles in plastic?
Silver nanoparticles are antibacterial, and when embedded in plastics for use in the medical field, are non-toxic. This makes silver nanoparticles useful in plastic applications such as surgical catheters.
Why are nanoparticles used in textiles?

How do you prepare nanoparticles?
There are a number of different synthetic routes to produce silver nano particles. One of these methods is the wet chemistry method. There are also several wet chemical methods for creating silver nanoparticles. Typically, these involve the reduction of a silver salt such as silver nitrate with a reducing agent like sodium borohydride in the presence of a colloidal stabilizer. Sodium borohydride has been used with polyvinyl alcohol, poly(vinylpyrrolidone), bovine serum albumin (BSA), citrate and cellulose as stabilizing agents. In the case of BSA, the sulfur-, oxygen- and nitrogen-bearing groups mitigate the high surface energy of the nanoparticles during the reduction. The hydroxyl groups on the cellulose are reported to help stabilize the particles. Citrate and cellulose have been used to create silver nanoparticles independent of a reducing agent as well. An additional novel wet chemistry method used to create silver nanoparticles took advantage of ß-D-glucose as a reducing sugar and a starch as the stabilizer.
