Abstract: There is provided a pressure sensing device and related methods, the pressure sensing device comprising, a plurality of chambers for storing one or more visual indicators, wherein the plurality of chambers are configured to release the one or more visual indicators when a pressure exerted on the plurality of chambers exceeds one or more pressure thresholds. The plurality of chambers can be microchambers. The device may be used in conjunction with a bandaging system to indicate the pressure applied onto a site of treatment.

Abstract: The present invention relates to a process for the production of a microcapsule comprising an active ingredient or inactive precursor thereof, as well as a microcapsule obtainable thereby. The process involves the use of a surface-reacted calcium carbonate as a template for encapsulating the active ingredient or inactive precursor thereof. The active ingredient or inactive precursor thereof is loaded onto the surface-reacted calcium carbonate and subsequently encased by a multilayer shell comprising at least two complementary layers using layer-by-layer assembly. Further aspects of the invention relate to the use of a surface-reacted calcium carbonate as a template for encapsulating the active ingredient or inactive precursor thereof, a product comprising said microcapsule, as well as the use of said microcapsule.

Abstract: Disclosed herein is a core-shell composite material comprising: a core optionally comprising an active ingredient compound; a shell structure comprising at least two alternating layers; the alternating layers being a protein layer and a polyphenol layer; and optionally a polyelectrolyte layer interfacing said core and said shell structure, said polyelectrolyte layer being disposed adjacent to said protein layer or said polyphenol layer, wherein said shell structure is selected to be resistant to degradation under gastric conditions but is degradable by one or more intestinal enzymes. In a preferred embodiment the protein is bovine serum albumin (BSA) or pepsin, the polyphenol layer is tannin or tannic acid, and the shell structure is degradable by pepsin.

Abstract: The present disclosure relates to a sensor for indicating food quality comprising a semi-permeable film layer, the semi-permeable film layer comprising at least one integrally formed well having at least one sensing element disposed therein; wherein the well is sealed by a second film layer, the semi-permeable film layer being impermeable to said sensing element but is permeable to at least one analyte detectable by said sensing element.
