    摘要： Methods of obtaining and kits that can be used to obtain an optical super-resolution image of a sample or a portion thereof or an individual or a portion thereof. In various examples, the individual is an individual with cancer. In various examples, a method includes contacting a sample or individual with one or more aluminosilicate nanoparticle(s) that have at least one organic fluorophore molecule covalently bonded to the aluminosilicate network of the nanoparticle(s), or a composition including the aluminosilicate nanoparticle(s); irradiating the sample or the individual, thereby exciting at least one of the fluorophore molecules of an individual aluminosilicate nanoparticle; and obtaining a fluorescence image or a sequence of fluorescence images, which can be processed to obtain a super-resolution image of the sample or the individual. In various examples, the sample is a biological sample, living or fixed tissues and/or cells, or a biopsy obtained from an individual.

    摘要： Methods of making blended, isoporous, asymmetric (graded) films (e.g. ultrafiltration membranes) comprising two or more chemically distinct block copolymers and blended, isoporous, asymmetric (graded) films (e.g. ultrafiltration membranes) comprising two or more chemically distinct block copolymers. The generation of blended membranes by mixing two chemically distinct block copolymers in the casting solution demonstrates a pathway to advanced asymmetric block copolymer derived films, which can be used as ultrafiltration membranes, in which different pore surface chemistries and associated functionalities can be integrated into a single membrane via standard membrane fabrication, i.e. without requiring laborious post-fabrication modification steps. The block copolymers may be diblock, triblock and/or multiblock mixes and some block copolymers in the mix may be functionally modified. Triblock copolymers comprising a reactive group (e.g., sulfhydryl group) terminated block and films comprising the triblock copolymers.

    摘要： Described is a versatile surface modification approach to, for example, modularly and orthogonally functionalize nanoparticles (NPs) such as, for example, PEGylated nanoparticles, ith various types of different functional ligands (functional groups) on the NP surface. It enables the synthesis of, for example, penta-functional PEGylated nanoparticles integrating a variety of properties into a single NP, e.g., fluorescence detection, specific cell targeting, radioisotope chelating/labeling, ratiometric pH sensing, and drug delivery, while the overall NP size remains, for example, below 10 nm.

    摘要： A film comprising a crystalline halide perovskite composition having the following formula: AMX3   (1) wherein: A is an organic cation selected from the group consisting of methylammonium, tetramethylammonium, formamidinium, and guanidinium; M is at least one divalent metal; and X is independently selected from halide atoms; wherein the crystalline film of the halide perovskite composition possesses at least one of an average grain size of at least 30 microns, substantial crystal orientation evidenced in an ordering parameter of at least 0.6, and a level of crystallinity of at least 90%. Methods for producing films of these halide perovskite compositions using ionic liquids instead of volatile organic solvents are also described herein.
