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.

Affinity-based detection of ligand-encoded synthetic biomarkers

Exemplary embodiments provide diagnostic devices, systems and methods for determining the presence or absence of one or more markers or characteristics in one or more samples. An exemplary diagnostic device may display a first two-dimensional machine-readable output to indicate the presence or absence of a first characteristic in a sample. Similarly, the exemplary diagnostic device may display a second two-dimensional machine-readable output to indicate the presence or absence of a second characteristic in a sample. An image capture device may be used to automatically detect the two-dimensional machine-readable output appearing in the diagnostic device. A computational device may be used to automatically determine whether the presence or absence of the first characteristic and/or the second characteristic based on the two-dimensional machine-readable output displayed in the diagnostic device.

Systems, devices and methods for multiplexed diagnostics

Systems, methods, and devices are provided for assessing DNA damage and repair in cells by measuring DNA migration under electrophoresis. In one exemplary embodiment, a microarray configured to hold cells in a predetermined spatial relationship is employed to improve accuracy, speed, and reliability of such measurements. In another embodiment, a self-contained cassette having a matrix material disposed therein can be used to create a substantially uniform environment for analyzing DNA damage and repair. Fluid can be circulated through the cell to assist in creating spatial patterns on the matrix material, or alternatively, the matrix material can already include a microarray pattern disposed thereon. Various methods and systems that take advantage of such microarrays and cassettes are also provided.
