What is a capping agent in nano chemistry?
Capping agents such as trisodium citrate are used to stop growth of nanoparticles and stabilise them from aggregation. Its effects are generally short lived though, it has been reported though that using trisodium citrate with the lee and miesel method can lead to particles that are stable for up to a month.
What is mean by alsever solution?
Alsever's solution is a saline-based liquid added to freshly collected blood to prevent coagulation and preserve the blood cells until needed. After adding Alsever's solution to the blood (1:1 volume ratio), the mix can be put at 4 degrees Centrigrade (refrigerator) for up to 10 weeks. I believe the ingredients are glucose (dextrose), sodium chloride, sodium citrate, and citric acid.
