Many of these are polymer dendrimers. Dendrimers just refer to the branching out of the chains, and is a very generic terms (we see them in “dendrites” too). But the amazing thing is that by having dendrimers we can substitute the different branches with functional groups, hormones and other molecules to change the physical property of the molecule. This doesn’t limit us to change the hydrophobic/hydrophilic nature of the particle, but also allows us to activate different pathways, or make them biodegradable. Sorry I have been missing the past few weeks, but I have been so busy learning! I will post some awesome uses for these nano particles in the next few weeks!
