Abstract: 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.

Abstract: Methods of determining the presence or absence or local concentration of an analyte in a sample or an individual or a portion thereof using ratiometric sensing and optical super-resolution microscopy (OSRM). The methods use aluminosilicate nanoparticles that can be used in OSRM. The analytes can be biologically relevant analytes, such as, for example, biologically relevant hydrogen ions, oxygen, reactive oxygen species, anions, nitric oxide, metal ions, anions, etc. The methods utilize averaging to address aluminosilicate nanoparticle homogeneity. The methods can be used in methods of treatment.

Abstract: The present disclosure is directed to methods of producing monosized protocells from monosized mesoporous silica nanoparticles (mMSNPs) and their use for targeted drug delivery formulations and systems and for biomedical applications. The present disclosure is also directed in part to a multilamellar or unilamellar protocell vaccine to deliver full length viral protein and/or plasmid encoded viral protein to antigen presenting cells (APCs) in order to induce an immunogenic response to a virus.
