"hydrogels exhibit strong swelling/ uncontrollable degradation restricting applications' long-term performance, overcome using nanocolloidal hydrogel... nanoparticles self-assemble into hydrophobic nanodomains preventing water uptake... UV-triggered polymerization photocrosslinked network interconnects nanoparticles while preserving internal hydrophobic phases, yielding transparent, mechanically tunable gels... long-term drug delivery, soft-tissue augmentation, implantables, wound healing, wearables"
