Particle packing into loose networks for tough and sticky composite gels
Scientific Reports, 2020 Hydrogel is an attractive material, but its application is limited due to its low mechanical strength. In this study, a tough composite gel could be prepared by synthesizing polymer particles within a polymer network having relatively loose cross-linking.

Stimuli-responsive lipid nanotubes in gel formulations for the delivery of doxorubicin
Colloids and Surfaces B: Biointerfaces, 2016 Lipid nanotubes (LNTs) are one of the most advantageous structures for drug delivery and targeting. LNTs formed by a specially designed molecule called AQUA (AQ-NH-(CH2)10COOH (AQ: anthraquinone group) is used for drug delivery, and doxorubicin (DOX) is the drug selected.
