The present invention is a composition that can form an edible film or an edible liquid coating that can be applied to the surface of fresh fish (fillets or cuts) or fresh seafood. The present invention acts as a physical barrier preventing oxygen, water and microorganisms from entering the food product, and also acts as a bacteriostatic and antioxidant agent.

A system for selective microcapsule extraction includes a non-planar core-shell microfluidic device. The non-planar core-shell microfluidic device generates microcapsules defining a core-shell configuration. A subset of the microcapsules contain aggregates, tissues, or at least one cell. A camera captures images of the microcapsules. A detection module includes a processor and a memory. The memory includes instructions that when executed by the processor causes the detection module to provide the images of the microcapsules as an input to a machine learning model. The machine learning model identifies microcapsules containing aggregates, tissues, or at least one cell. A force generator generates a force to extract the microcapsules. A microcontroller selectively activates the force generator to generate the force when the detection module identifies a microcapsule containing aggregates, tissues, or at least one cell to extract the microcapsule.

Graphene oxide aerogel beads (GOABs) are formed that have a core/shell structure where a smooth shell covers a multi-layer core. The smooth shell and the layers of the multilayer core comprise graphene oxide or reduced graphene oxide. The GOABs can include a phase-change material encapsulated within the multi-layer core. The GOABs can be combined or decorated with Fe.sub.3O.sub.4 nanoparticles or MoS.sub.2 microflakes for various applications. The GOABs are formed from aqueous slurries of graphene oxide that is extruded as drops into an aqueous solution of a coagulant where GOABs are formed. The GOABs are washed and freeze dried, after which, the GOABs can be reduced as desired by chemical or thermal means. Impregnation can be carried out with the phase-change material.

The invention relates to [1] an aqueous microcapsule dispersion containing a component (A): microcapsules each having a shell and a core containing at least one organic compound inside the shell, and a component (B): a surfactant containing a quaternary ammonium salt compound represented by the general formula (1), wherein the ratio by mass of the content of the component (A) to the content of the component (B) [component (A)/component (B)] is 0.1 or more and 20 or less, and [2] a dispersant for microcapsules, containing a surfactant that contains a quaternary ammonium salt compound represented by the general formula (1).

A first aspect of the invention refers to a method for producing a hydrogel microsphere, the method comprising the steps of: a. generating by means of a capillary a droplet of controlled size of a first fluid in a gaseous phase, b. dispensing said droplet of a first fluid into a recipient comprising a second fluid, wherein the first fluid is immiscible with the second fluid and wherein the density of the second fluid is lower than the density of the first fluid, c. contacting the droplet of the first fluid with the second fluid, thereby producing a hydrogel microsphere, d. recovering the hydrogel microsphere from the second fluid for storage. A second aspect of the nvention is directed to a hydrogel microsphere obtainable by the method according to the first aspect of the invention. A further aspect of the invention refers to a system for producing a hydrogel microsphere according to any of the second and third aspect.
