NanoVision Diagnostics


The NanoVision Diagnostics system assesses molecular changes in nuclear DNA from a standard biopsy slide. The genetic and epigenetic changes that induce cancer also change chromatin structure. NanoVision Diagnostics has developed a novel method of measuring changes in chromatin structure.  Chromatin structural changes have been shown to correlate with cancer in multiple clinical studies.

The NanoVision Diagnostics system is 1000 times more sensitive than an optical microscope, allowing it to measure molecular scale changes in DNA structure. Multiple clinical studies demonstrate these changes correlate with cancer in multiple organ systems. The NanoVision Diagnostics system generates an objective graphical output and numerical score to guide physicians in cancer treatment decisions.


Since patients with positive optical biomarkers are more likely to progress to cancer, the NanoVision Diagnostics system:
