Hydrogel Microcapsules: Hydrogel Microcapsules with a Thin Oil Layer: Smart Triggered Release via Diverse Stimuli (Adv. Funct. Mater. 18/2021)

Supramolecular hydrogel microcapsules via cucurbit[8]uril host-guest interactions with triggered and UV-controlled molecular permeability.

Host-guest assembly in droplet-based microfluidics opens a new avenue for fabricating supramolecular hydrogel microcapsules with high monodispersity and controlled functionality. In this paper, we demonstrate a single emulsion microdroplet platform to prepare microcapsules with supramolecular hydrogel skins from host molecule cucurbit[8]uril and guest polymer anthracene-functionalized hydroxyet...

Core-shell hydrogel microcapsules for improved islets encapsulation.

Islets microencapsulation holds great promise to treat type 1 diabetes. Currently used alginate microcapsules often have islets protruding outside capsules, leading to inadequate immuno-protection. A novel design of microcapsules with core-shell structures using a two-fluid co-axial electro-jetting is reported. Improved encapsulation and diabetes correction is achieved in a single step by simpl...

Layer-by-layer thin films and microcapsules for biosensors and controlled release.

We present an overview of the preparation and properties of layer-by-layer (LbL) deposited thin films and microcapsules in relation to their use in the development of biosensors and controlled release systems. Enzyme biosensors can be constructed by immobilizing enzymes on the surface of electrodes by LbL deposition without loss of their catalytic activity. In addition to synthetic polymers, ...

Biodegradable polymeric microcapsules for selective ultrasound-triggered drug release

One-pot microfluidic fabrication of graphene oxide-patched hollow hydrogel microcapsules with remarkable shell impermeability.

Uniform hollow hydrogel microcapsules, composed of a graphene oxide platelet-patched shell, are fabricated in one step in a capillary-based microfluidic device. We demonstrate that patching a small amount of graphene oxide at the interfaces remarkably prevents the leakage of small molecules through the shell.
