Abstract: There is provided a multimodality method and a system for printing a three-dimensional (3D) construct or part thereof, the method comprising: (i) supporting a flowable precursor with a flowable support at a position that allows said flowable precursor to be crosslinked through irradiation by an irradiation source; (ii) depositing one or more materials on/within the flowable precursor; and (iii) crosslinking through irradiation by the irradiation source, at least part of the flowable precursor that is in contact with the one or more materials in the flowable precursor to form the 3D construct or part thereof.

Abstract: There is provided an attachment configured to detachably couple to a fluid extruding device, the attachment comprising: a membrane having a plurality of pores configured to allow a cell to pass through while inducing a mechanical stress to the cell such that the introduction of one or more substances into the cell is facilitated; and an engaging member for coupling to the outlet of the fluid extruding device such that the membrane is in fluid communication with the outlet of the fluid extruding device, wherein the fluid extruding device is configured to extrude fluid via mechanical actuation.

Abstract: The present invention relates, in general terms, to hydrogels and their uses thereof. The hydrogels demonstrate toughness; i.e. the ability to absorb energy and plastically deform without fracturing. The present invention also relates to methods of fabricating hydrogels. In particular, the method of fabricating a tough hydrogel comprises polymerising a plurality of charged monomers in the presence of multivalent ions in order to form an ion impregnated hydrogel and exposing the ion impregnated hydrogel to heat in order to form the tough hydrogel.
