Cryogel 3D scaffolds and methods for producing thereof

A method of producing a cryogel-based multicompartment 3D scaffold is herein disclosed. The method comprises the steps of: a) providing a first frozen polymeric layer on a refrigerated support kept at subzero temperature; b) providing subsequent polymeric layers to obtain a stack of polymeric layers by possibly modulating the subzero temperature of the refrigerated support; c) optionally incubating the final polymeric structure at subzero temperature; and d) placing the produced cryogel at a temperature above 0° C., the method being characterized in that each subsequent layer i) is deposited on the previous one after freezing of this latter; ii) is deposited on the previous one before the complete polymerization of this latter; and iii) is deposited with a temperature higher than the freezing temperature of the previously deposited layer. Cryogel scaffolds obtained from the method of the invention are also disclosed.

METHOD OF MANUFACTURING MECHANORECEPTION STIMULATION FABRIC
20220133663 · 2022-05-05 ·

A method for manufacturing a mechanoreception fabric for incorporation into a garment or item of apparel sets a liquid substrate to a fabric weave to produce a plurality of protuberances in graticulate array and spaced apart across a surface of the fabric. The plurality of protuberances includes pyramidal nodes, each independent and separate from other nodes, not less than 1 mm apart at the base and not more than 5 mm apart at each apex and 1.5 mm in height. Because the nodes are separated and not in contact with each other, the fabric produced is still stretchable and wearable when incorporated into an item of apparel despite the nodes having a hardness of between Shore A 60 and 80.
