Abstract

Nature-inspired smart materials offer numerous advantages over environment-friendliness and efficiency. Emulating the excellent adhesive properties of mussels foot proteins, where the Lysine is in close proximity with the 3, 4-dihydroxy-L-phenylalanine (DOPA), embodiments report the synthesis of a novel photo-curable peptide-based adhesive consisting exclusively of these two amino acids. The adhesive is a highly concentrated aqueous solution of a monomer, a crosslinker and a photoinitiator. No toxicity of the adhesive was observed when the cytocompatibility on human dermal fibroblast cells was assessed. Lap-shear adhesion measurements on plastic and glass surfaces and comparison with different types of commercial adhesives showed that the adhesive strength of the disclosed glue is comparable when applied in the air and superior when used underwater. Given the convenience of the facile synthesis, biocompatibility, ease of application underwater and high adhesive strength, embodiments expect that the adhesive may find application, but not limited, to the biomedical field.

An example of a method of such processing may include: supplying a first reaction medium including an iodine species and a first catalyst, wherein the first catalyst includes a first deep eutectic solvent, a first ionic liquid, or a first mixture of both; contacting the reaction medium with a first sulfur species, wherein the first sulfur species includes hydrogen sulfide, a sulfur-containing hydrocarbon, or any combination thereof; and reacting the first sulfur species with the reaction medium to produce a second sulfur species, hydrogen iodide, or a combination thereof.

Abstract

Systems and methods for correcting NMR T2 times are disclosed. The method may include creating a plurality of 3D rough surface pore models, where each 3D rough surface pore model includes a rough surface, for each of the plurality determining a pore roughness coefficient (PRC) and a volume; and simulating a first T2 relaxation time based on the 3D rough surface pore model. The method may further include determining a smooth surface pore model, with the same volume as the 3D rough surface pore model, and simulating a second T2 relaxation time based on the smooth surface pore model. The method may still further includes determining a T2 rough surface correction factor based on the first and the second T2 relaxation times, and forming a data pair comprising the pore roughness coefficient (PRC) and the T2 rough surface correction factor; and fitting a T2 correction curve to the data pairs.

Abstract

Compositions and methods are provided, for site-specific modification of a target DNA. Compositions, herein "PNP editors" for targeted DNA modification, (a) include site- directed modifying polypeptides, in some forms with nuclease activity, and in other forms without nuclease activity; (b) DNA-targeting RNA or DNA, herein, guide oligonucleotides and (c) a selected PNA. The DNA-targeting RNA or DNA and its site-directed modifying polypeptide (i.e., site-directed polypeptide) form a complex (i.e., bind via non-covalent interactions). The DNA-targeting RNA or DNA provides target specificity to the complex by comprising a nucleotide sequence that is complementary to a sequence of a target DNA. The site-directed modifying polypeptide of the complex provides the site-specific activity. Methods for site-specific modification of a target DNA and/or a polypeptide associated with the target DNA includes contacting the target nucleic acid with the disclosed compositions.
