Abstract
Colloidosomes are microcapsules whose shells are composed of cumulated or fused colloidal particles. When colloidosomes are used for in situ encapsulation, it is still a challenge to achieve a high encapsulation efficiency and controllable release by an effective fabrication method. Herein, we present a highly efficient route for the large-scale preparation of colloidosomes. The biodegradable polylactic acid (PLA) nanoparticles (NPs) as shell materials can be synthesized using an antisolvent precipitation method, and the possible formation mechanism was given through the molecular dynamics (MD) simulation. The theoretical values are basically consistent with the experimental results. Through the use of the modified and unmodified PLA NPs, the colloidosomes with controllable shell porosities can be easily constructed using spray drying technology. We also investigate the mechanism of colloidosomes successfully self-assembled by PLA NPs with various factors of inlet temperature, feed rate, and flow rates of compressed air. Furthermore, avermectin (AVM) was used as a model for in situ encapsulation and a controllable release. The spherical modified colloidosomes encapsulating AVM not only achieve a small mean diameter of 1.57 μm but also realize a high encapsulation efficiency of 89.7% and impermeability, which can be further verified by the MD simulation. AVM molecules gather around and clog the shell pores during the evaporation of water molecules. More importantly, the PLA colloidosomes also reveal excellent UV-shielding properties, which can protect AVM from photodegradation.

Abstract
Pickering emulsions (particle-stabilized emulsions) have been widely explored due to their potential applications, one of which is using them as precursors for the formation of colloidal capsules that could be utilized in, among others, the pharmacy and food industries. Here, we present a novel approach to fabricating such colloidal capsules by using heating in the alternating magnetic field. When exposed to the alternating magnetic field, magnetic particles, owing to the hysteresis and/or relaxation losses, become sources of nano- and micro-heating that can significantly increase the temperature of the colloidal system. This temperature rise was evaluated in oil-in-oil Pickering emulsions stabilized by both magnetite and polystyrene particles. When a sample reached high enough temperature, particle fusion caused by glass transition of polystyrene was observed on surfaces of colloidal droplets. Oil droplets covered with shells of fused polystyrene particles were proved to be less susceptible to external stress, which can be evidence of the successful formation of capsules from Pickering emulsion droplets as templates.

Abstract
Colloidosomes are micrometer-sized hollow particles that have shells consisting of coagulated or fused colloid particles. While many large colloidosomes with sizes well above 1.0 μm have been prepared, there are fewer examples of submicrometer colloidosomes. Here, we establish a simple emulsion templating-based method for the preparation of robust submicrometer pH-responsive microgel colloidosomes. The colloidosomes are constructed from microgel particles based on ethyl acrylate and methacrylic acid with peripheral vinyl groups. The pH-responsive microgels acted as both a Pickering emulsion stabilizer and macro-cross-linker. The emulsion formation studies showed that the minimum droplet diameter was reached when the microgel particles were partially swollen. Microgel colloidosomes were prepared by covalently interlinking the microgels adsorbed at the oil-water interface using thermal free-radical coupling. The colloidosomes were prepared using a standard high-shear mixer with two different rotor sizes that corresponded to high shear (HS) and very high shear (VHS) mixing conditions. The latter enabled the construction of submicrometer pH-responsive microgel-colloidosomes on the gram scale. The colloidosomes swelled strongly when the pH increased to above 6.0. The colloidosomes were robust and showed no evidence of colloidosome breakup at high pH. The effect of solute size on shell permeation was studied using a range of FITC-dextran polymers, and size-selective permeation occurred. The average pore size of the VHS microgel-colloidosomes was estimated to be between 6.6 and 9.0 nm at pH 6.2. The microgel-colloidosome properties suggest that they have the potential for future applications in cosmetics, photonics, and delivery.
