According to recent research from Parkville, Australia, "We report the assembly of low-fouling polymer capsules with engineered deconstruction properties by using a combination of layer-by-layer (LbL) assembly and click chemistry. Preformed, hydrogen-bonded multilayers of alkyne-functionalized poly(N-vinyl pyrrolidone) (PVPONAlk) and poly(methacrylic acid) (PMA) assembled at pH 4 on silica particles were cross-linked with a bisazide linker (containing a disulfide link) through alkyne-azide click chemistry."
"Following dissolution of the silica template particles, and altering the solution pH to 7.2 to disrupt hydrogen bonding between PVPONAlk and PMA to effect ...
