Are the microparticles in a suspension sterile? Or is it possible to sterilize the suspension?
1 answer-
The polystyrene microparticles offered for sale are not sterile.
Although autoclaving is a common method of sterilization, polystyrene microparticles are not autoclavable. Filter sterilization is also not a practical method. There are no available protocols for sterilizing polystyrene microparticles. From the remaining methods for sterilization, it should be possible to sterilize in 70% ethanol for 30 minutes and then rinse away the ethanol with sterile water. For small batches, UV radiation would be another option.Helpful?

What kind of surface modification are performed on these particles?
1 answer-
These particles possess a negative charge and have residual sulfate end groups as a result of the manufacturing process. This is not considered to be a functional group as would a carboxyl-, aldehyde-, or amine-functionalized product.
