Reversible and Large‐Scale Cytomimetic Vesicle Aggregation: Light‐Responsive Host–Guest Interactions

Optical properties of amphiphilic copolymer-based self-assemblies

“…Another unique feature named photo-induced fusion was observed for vesicles self-assembled from azobenzene-containing copolymers [99][100][101][102][103]. Zhang et al prepared polymer vesicles through self-assembly of an amphiphilic diblock copolymer composed of poly(N-isopropyl acrylamide) and polyacrylate with azobenzene pendant on the side-chains [100].…”

Selective Metal-Ion-Mediated Vesicle Adhesion Based on Dynamic Self-Organization of a Pyrene-Appended Glutamic Acid

“…[7][8][9] Groups like Zhou, Ravoo, Webb contributed many excellent works to this field. [4][5][6][7][8][9][10][11][12][13] Utilizing various non-covalent interactions like host-guest, metal-ligand coordination and hydrogen bonding, the molecular recognition can be realized on the vesicle membranes, which allows for the occurrence of membrane fusion or vesicle adhesion. [10][11][12][13] Among these strategies, embedding metal receptors in the vesicle membranes to fabricate metal ionresponsive vesicle membrane fusion/aggregation system is a convenient and cost effective pathway.…”

[14][15][16][17] Furthermore, metal-coordination induced vesicle aggregation could help people better understand the role of metal ions in cell membrane movement due to the fact that phospholipids in cell membranes are capable of forming complexes with some specific metal ions like calcium ion.…”

Nanoassemblies driven by cyclodextrin-based inclusion complexation

“…Using light-responsive CD-AZO interactions as driving forces, reversible and large-scale cytomimetic vesicle aggregation was also realized by Yan et al 35 Firstly, vesicles functionalized with b-CD or AZO were prepared respectively. The two kinds of vesicles then aggregated through multivalent intervesicular host-guest interactions between the CD and AZO groups (Fig.…”
