Abstract: In some aspects, the disclosure relates to compositions and method for detection, classification, and treatment of cancer. In some embodiments, the disclosure relates to protease imaging sensors comprising a scaffold linked to an enzyme-specific substrate that includes a first detectable marker capable of being released from the prostate protease sensor when exposed to an enzyme present in cancer and a tumor imaging agent comprising a second detectable marker that is linked to the scaffold. In some embodiments, the disclosure relates to methods of monitor progression of a tumor in a subject based upon detection of detectable markers in a sample obtained from a subject who has been administered a protease imaging sensor, upon detection of a tumor imaging agent, or any combination thereof.

Abstract: This disclosure provides a method and compositions for substantially increasing the concentration of DNA in macrophages of a patient. By administering to a patient one or more agents which prevent the activity of deoxyribonucleases within lysosomes of macrophages, degradation of DNA phagocytosed by macrophages is temporarily blocked, permitting its accumulation. This strategy has the potential to enhance the detection of genetic biomarkers from cells typically phagocytosed by macrophages, such as tumor cells, and thus has applications for early or residual detection of cancer.

Abstract: The invention relates to methods and products associated with in vivo enzyme profiling. In particular, biomarker nanoparticles capable of quantitatively detecting enzymatic activity in vivo are described. These nanoparticles can be used to detect in vivo enzyme activity. The invention also relates to products, kits, and databases for use in the methods of the invention.

Abstract: This disclosure provides a method for substantially increasing the concentration of cfDNA in a patient. By injecting a patient with lipid and/or polymer nanoparticles, agents that bind cfDNA, or inhibit deoxyribonucleases prior to collection of a sample of cfDNA, e.g., by way of a liquid biopsy, major pathways for the degradation of cfDNA are temporarily blocked, permitting transient accumulation of cfDNA. This strategy has the potential to dramatically enhance the quality of detection achieved by downstream cfDNA e analytical applications, such as sequencing applications.
