TL;DR: Dendrimersomes marry the stability and mechanical strength obtainable from polymersomes with the biological function of stabilized phospholipid liposomes, plus superior uniformity of size, ease of formation, and chemical functionalization, providing access to systematic tuning of molecular structure and of self-assembled architecture.
Journal ArticleDOI

TL;DR: The results demonstrated the candidacy of glycodendrimersomes as new mimics of biological membranes with programmable glycan ligand presentations, as supramolecular lectin blockers, vaccines, and targeted delivery devices.
Journal ArticleDOI
Predicting the Size and Properties of Dendrimersomes from the Lamellar Structure of Their Amphiphilic Janus Dendrimers
TL;DR: An inverse proportionality between size, stability, mechanical properties of dendrimersomes, and thickness of their membrane was discovered and a methodology to predict the size of the dendedrimersome based on this correlation was developed.
Journal ArticleDOI

TL;DR: It is shown that both homochiral and racemic perylene bisimide compounds, including a mixture of 21 diastereomers that cannot be deracemized at the molecular level, self-organize to form single-handed helical assemblies with identical single-crystal-like order, and proposed that this high crystalline order is generated via a cogwheel mechanism that disregards the chirality of the self-assembling building blocks.
