The apparatuses and methods described herein relates generally to the field of active agent (drug) release from surgical grafts useful for soft tissue reconstruction, regeneration, or repair. More particularly, described herein are surgical grafts for soft tissue repair that include an active agent that is released over time while advantageously matching the biomechanical properties of tissue during healing and recovery.

The present invention is directed to a curable polymer comprising: a base acrylic monomer (monomer A); a monomer with bioactive functionality (monomer B); a monomer containing a cross-linker (monomer C). The present invention also relates to a method of making a polymer coating on a solid support. The present invention also relates to a method of preserving a product.

A solar and thermal regulating window structure including: an optically-transparent housing frame; a reversible liquid absorbent material layer positioned in the housing frame; a thermally-reflective layer having high solar transmittance and high thermal reflectance positioned over the liquid absorbent material layer; a liquid, being absorbed in the liquid absorbent material layer below a selected transition temperature, and being positioned over the liquid absorbent material layer above the selected transition temperature, such that when below the selected transition temperature, the window structure facilitates indoor solar heating through solar transmittance during daytime and facilitates indoor heat insulation through thermal reflectance during daytime and nighttime, when above the selected transition temperature, the window structure facilitates indoor heat dissipation through thermal emission; and an optical film with high transmittance for both solar and thermal radiation, configured to seal the liquid absorbent material layer, liquid, and thermally-reflective layer in the housing frame. The window structure enables passive all-day thermal management in different climates.

A composite material (and its manufacture) is described that has (i) a first layer comprising an absorbent fiber material that is in contact with the area of use on its first side, (ii) a second layer comprising an absorbent material, said second layer being arranged on the second side of said first layer, wherein a plurality of channels extends through the entire first layer, from said first side to said second side thereof, and further extends into at least a portion of said second layer. This composite is of particular use in wound treatment.

The present invention relates to devices including microfluidic devices, e.g. Skin on-Chip (Skin-Chip), for simulating a physiological response to agents and injury, including tattoo injury. In particular, a Skin-Chip is intended for use in replicating the interaction of tattoo ink with skin on a cellular level, including but not limited to mechanisms of wound healing following a tattoo gun and/or tattoo needle induced skin injury; ink particle effects such as pigment retention, pigment distribution and pigment clearance; inflammatory response to foreign particles, i.e. tattoo ink, etc. Further, effects of tattoo inks on simulated microfluidic skin is extended to determine effects of systemic ink exposure upon other organs through use of organ chips, e.g. liver-chips, kidney-chips, Lymph node-chips, etc. In some embodiments, safer ink formulations, e.g. less toxic ink particles, less toxic ink diluents, etc., are contemplated for development and use over currently available tattoo inks and diluents. Further contemplated is using a Tattooed Skin-Chip for developing rapid and non-toxic methods of removal of Tattoos in human skin.

A multilayer structure comprising solid layers and defining at least one gap that separates the solid layers to form an alternating pattern of the solid layers and the at least one gap in the structure.

A subtractive method for structuring a hydrogel, comprising the following steps: producing a hydrogel layer containing benzophenone (3) on a substrate (6), the hydrogel not having any photocleavable group; bringing the hydrogel layer into contact with an oxygen tank (4); selectively illuminating the hydrogel layer with a light (5) capable of activating the benzophenone in order to convert the illuminated zone of the hydrogel layer into a liquid; and eliminating the liquid.
