HYDROGELS

Precise patterning driven by droplets

Hydrogels that can respond to multiple external stimuli are typically prepared as a single or interpenetrated polymer network material. Now, water-in-oil droplet networks have been used to precisely pattern different stimuli-responsive materials into well-ordered, continuous hydrogel structures.
