    摘要: Organic charge-transfer (CT) co-crystals in a crossed stack system are disclosed. The co-crystals exhibit bidirectional charge transfer interactions where one donor molecule shares electrons with two different acceptors, one acceptor face-to-face and the other edge-to-face. The assembly and charge transfer interaction results in a pleochroic material whereby the optical absorption continuously changes depending on the polarization angle of incident light.

    摘要: Organic charge-transfer (CT) co-crystals in a mixed stack system are disclosed, wherein a donor molecule (D) and an acceptor molecule (A) occupy alternating positions (DADADA) along the CT axis. A platform is provided which amplifies the molecular recognition of donors and acceptors and produces co-crystals at ambient conditions, wherein the platform comprises (i) a molecular design of the first constituent (α-complement), (ii) a molecular design of the second compound (β-complement), and (iii) a solvent system that promotes co-crystallization.

    摘要: Disclosed herein are novel peptide amphiphile molecules and compositions composed of a peptide sequence that non-covalently binds the growth factor TGF-β1. Also disclosed are methods of using these peptide amphiphiles to create a gel scaffold in situ that enhances articular cartilage regeneration when used in combination with microfracture. Significant improvement in tissue quality and overall O'Driscoll histological scores were observed in rabbits with full thickness articular cartilage defects treated with the TGF-binding peptide amphiphile. The gel can further serve as a delivery vehicle for recombinant TGF-β1 protein growth factor. Scaffolds that localize and retain chondrogenic growth factors may synergistically enhance cartilage repair when combined with microfracture, by inducing bone marrow mesenchymal stem cells into chondrogenic differentiation. This invention represents a promising new biomimetic approach to enhance current techniques of articular cartilage regeneration in the clinical setting.
