Abstract: Provided herein are methods of detecting a disease, condition, or disorder in a subject. In some embodiments, the methods include obtaining a set of ribonucleic acid (RNA) molecules from a population of exosomes in a biological sample obtained from the subject and detecting a plurality of target RNA molecules corresponding to a selected set of cell-specific exosomal RNA molecules in the set of RNA molecules to generate a target RNA molecular profile for the sample. In some of these embodiments, the methods also include determining that the target RNA molecular profile substantially matches a reference RNA molecular profile that correlates with the disease, condition, or disorder in a subject and/or using at least one algorithm that predicts a likelihood that the target RNA molecular profile correlates with the disease, condition, or disorder in a subject. Related biosensor devices, kits, and systems are also provided.
Abstract: Methods for analyzing DNA-containing samples are provided. The methods can comprise isolating a single genomic equivalent of DNA from the DNA-containing sample to provide a single isolated DNA molecule. The single isolated DNA molecule can be subjected to amplification conditions in the presence of one or more sets of unique molecularly tagged primers to provide one or more amplicons. Any spurious allelic sequences generated during the amplification process are tagged with an identical molecular tag. The methods can also include a step of determining the sequence of the one or more amplicons, in which the majority sequence for each code is selected as the sequence of the single original encapsulated target. The DNA-containing sample can be a forensic sample (e.g., mixed contributor sample), a fetal genetic screening sample, or a biological cell.

Abstract: The present invention provides novel biomaterial compositions and methods having a technology to improve retention of hyaluronic acid (HA). The biomaterial compositions utilize small HA binding peptides and extracellular matrix binding (ECM) peptides that are tethered to synthetic biocompatible polymers. When tethered to the polymers, the peptide region allows the polymers to bind to HA and to tissues such as cartilage. The novel biomaterial compositions can be used to coat or chemically modify cartilage or tissues with a biologically compatible polymer having HA binding peptides, which allow HA to bind to the surface of the cartilage or tissues. Methods of using same are also provided.
