## Abstract A well‐defined, high‐density poly(__N__‐isopropylacrylamide) (PNIPAM) brush was fabricated through a novel and reliable strategy by the combination of the self‐assembly of a monolayer of dendritic photoinitiator and surface‐initiated photopolymerization. The whole fabrication process of
## Abstract **Summary:** Biodegradable poly(1,5‐dioxepan‐2‐one) (PDXO) was grown __directly__ from SiOH groups of a silica nanoparticle by surface‐initiated, ring‐opening polymerization (SI‐ROP) of 1,5‐dioxepan‐2‐one (DXO). The direct SI‐ROP of DXO was achieved by heating a mixture of Sn(Oct)~2~,
