The present disclosure in some aspects relates to methods and compositions for accurately detecting and quantifying multiple analytes present in a biological sample. In some aspects, the methods and compositions provided herein address one or more issues associated with the stability and/or size of nucleic acid structures such as rolling circle amplification products in the biological sample.

Provided herein, in some aspects, are methods of imaging molecules without a microscope or other specialized equipment, referred to herein as “microscope-free imaging (MFI).” Herein, “molecular instruments” (e.g., DNA-based and protein-based molecules) are used, instead of microscopes, in a “bottom-up” approach for inspecting molecular targets.

Methods and compositions for in situ detection of circular RNA in a tissue sample are provided.

The invention provides systems and methods for rapid automated identification of microbes and antimicrobial susceptibility testing (AST) directly from a patient specimen, without specimen preparation. Specimens are loaded into an analytical cartridge for processing. Analytical cartridges are preloaded with species-specific labels that are used to identify and enumerate microbes in the specimen. Instruments, such as analyzers can be used to interact with analytical cartridges to carry out methods of the invention all within the cartridge.
