How droplet microfluidics can be used to fabricate solid‐shelled microcapsules having precisely controlled release behavior is described. Glass capillary devices enable the production of monodisperse double emulsion drops, which then as templates for microcapsule formation. The exquisite control afforded by tune compositions and geometrical characteristics with exceptional precision. use this approach that only their contents when exposed a specific stimulus – such change in temperature,...

Encapsulation of bioactive materials and drugs using the emulsion electrospinning method.
Bringing droplets to life: A cytoskeletal protein (red dots, see scheme) is expressed in artificial cells composed of biocompatible polymersomes, which encapsulate expression machinery and amino acid building blocks. Release the proteins can be triggered by a negative osmotic shock.
We use a microfluidic device to prepare monodisperse amphiphilic particles in the shape of crescent-moon and these stabilize oil droplets water. The is comprised tapered capillary theta (θ) that injects two phases into water single receiving capillary. One fluorocarbon, while second photocurable monomer, which partially wets first drop; silica colloids monomer migrate adsorb interface with but do not protrude interface. Upon UV-induced polymerization, solid crescent moon are formed; removal...
We present a new type of microcapsule programmed with tunable active release mechanism. The capsules are triggered by plasticizing stimulus that induces phase change transition the polymeric membrane from solid to fluidized form; thereafter, cargo is actively driven out capsule through defect at wall controllable kinetics. Tuning degree fluidity tailoring amount allows us obtain temporal variation kinetics subsecond abrupt burst slow sustained encapsulant over many minutes. Moreover, we...
Colloidal capsules can sustain an external osmotic pressure; however, for a sufficiently large pressure, they will ultimately buckle. This process be strongly influenced by structural inhomogeneities in the capsule shells. We explore how time delay before onset of buckling decreases as shells are made more inhomogeneous; this behavior quantitatively understood coupling shell theory with Darcy's law. In addition, we show that inhomogeneity dramatically change folding pathway taken after it buckles.
We report a microfluidic approach to produce monodisperse pH-responsive microcapsules with precisely controlled release behavior. The solid microcapsule shells are composed of biocompatible polymer and robustly encapsulate an active material; however, when exposed trigger pH, the degrade ultimately contents. control pH by using polymers that dissolve at different values. independently time which contents released carefully controlling shell thickness. Moreover, we rate encapsulated making...
Fragrances are amphiphilic and highly volatile, all of which makes them a challenging cargo to efficiently encapsulate retain in microcapsules using traditional approaches. We address these limitations by introducing new strategy that combines bulk microfluidic emulsification: stable fragrance-in-water (F/W) emulsion is primarily prepared from emulsification incorporated within polymer microcapsule via emulsification. On the basis in-depth study physicochemical properties on fragrance...
High internal phase emulsions (HIPE) prepared using whey protein microgels (WPMs) as a surfactant were demonstrated to have substantially higher stability than HIPEs similar loadings of non-gelled isolate (WPI) or Tween 20. Microgel colloids from WPI solutions by heat treatment at 85 °C in narrow pH range (5.8-6.0) particle sizes approximately 90, 160 and 350 nm diameter. ζ-potentials the WPM increased negativity with decreasing size -7.4 ± 2.5 down -21.1 0.9 90 nm. All WPMs conferred high...
In this work, we present gel-in-gel water-in-oil (W/O) high internal phase emulsions (HIPEs) that feature stability by structuring both phases of the emulsion. Compared to significant advances made in oil-in-water (O/W) HIPEs, W/O HIPEs are extremely unstable and difficult generate without introducing concentrations surfactants. Another main challenge is low viscosity water oil which promotes instability HIPEs. Here, demonstrate ultrastable biphasic structuring, hydrogels dispersed oleogels,...
Nucleic acid amplifications, such as polymerase chain reaction (PCR), are very beneficial for diagnostic applications, especially in the context of bacterial or viral outbreaks due to their high specificity and sensitivity. However, need bulky instrumentation complicated protocols makes these methods expensive slow, particularly low numbers RNA DNA templates. In addition, implementing conventional nucleic amplification a high-throughput manner is both reagent- time-consuming. We bring...

Conventional delivery systems for hydrophilic material still face critical challenges toward practical applications, including poor retention abilities, lack of stimulus responsiveness, and low bioavailability. Here, we propose a robust encapsulation strategy cargo to produce wide class aqueous core–shell–shell coconut-like nanostructures featuring excellent stability multifunctionality. The numerous active groups (−SH, −NH2, −COOH) the protein–polysaccharide wall enable formation...
Hemp seed protein isolates (HPI) were extracted from seven commercial hemp cultivars, a Cornell breeding line, and heart product, their composition functional properties investigated. HPI contained different ratios of edestin, vicilin, albumin proteins, which affected solubility functionality. Higher was associated with cultivars that more vicilin albumin, influenced the subsequent HPI. Significant differences in water holding capacity (0.83-1.05 g water/g isolate), oil (1.28-1.81 oil/g foam...
