Bioink compositions comprising a biomaterial (mammalian, plant based, synthetically derived, or microbially derived) such as a hydrogel and a microbial-, fungal-, or plant-produced polysaccharide, with or without cells, for use in the 3D bioprinting of human tissues and scaffolds are described. The bioink compositions have excellent printability and improved cell function, viability and engraftment. Furthermore, the bioink compositions can be supplemented through the additional of auxiliary proteins and other molecules such as growth factors including extracellular matrix components, Laminins, super affinity growth factors and morphogens. The bioink compositions can be used under physiological conditions related to 3D bioprinting parameters which are cytocompatible (e.g. temperature, printing pressure, nozzle size, bioink gelation process). The combination of a biogum-based biomaterial together with mammalian, plant, microbial or synthetically derived hydrogels exhibited improvement in printability, cell function and viability compared to tissues printed with bioink not containing biogums.

Terminal hydroxylated acrylates and methacrylates were prepared by catalytic transesterification of acrylates and methacrylates with diols catalyzed by a system of a tetranuclear zinc alkoxide, [Zn(tmhd)(OMe)(MeOH)]4 (1a), with 4 equiv. of 2,2′-bipyridine (L1). The reaction time to reach the equilibrium state was analyzed by kinetic studies and a curve-fitting analysis based on the Runge-Kutta method for optimizing the best reaction conditions for mono-esterification. In addition to these kinetic analyses, DFT calculations estimated a proposed mechanism of the catalytic transesterification. This journal is

Supramolecularly Engineered Amphiphilic Macromolecules: Molecular Interaction Overrules Packing Parameters

supporting information, p. 3516 - 3520 (2017/03/21)
We report molecular interaction-driven self-assembly of supramolecularly engineered amphiphilic macromolecules (SEAM) containing a single supramolecular structure-directing unit (SSDU) consisting of an H-bonding group connected to a naphthalene diimide chromophore. Two such SEAMs, P1-50 and P2-50, having the identical chemical structure and hydrophobic/hydrophilic balance, exhibit distinct self-assembled structures (polymersome and cylindrical micelle, respectively) due to a difference in the H-bonding group (hydrazide or amide, respectively) of the single SSDU. When mixed together, P1-50 and P2-50 adopted self-sorted assembly. For either series of polymers, variation in the hydrophobic/hydrophilic balance does not alter the morphology reconfirming that self-assembly is primarily driven by directional molecular interaction which is capable of overruling the existing norms in packing parameter-dependent morphology control in an immiscibility-driven block copolymer assembly.
