Techniques like ATRP (Atom Transfer Radical Polymerization) and RAFT (Reversible Addition-Fragmentation Chain Transfer) allow scientists to build polymers with exact molecular weights.

Biodegradable polymer scaffolds provide a temporary 3D structure that guides cellular growth and tissue regeneration before safely dissolving in the body. 7. Conclusion
