The present invention employs the technique for expansion microscopy (E×M) utilizing anchorable derivatives of hematoxylin and eosin (H&E) stained tissue specimens within tissue samples, in order to achieve high resolution detection of biomolecules with precise morphological features of cells and nuclei, which in turn, allows for effective for accurate early stage disease diagnosis including various cancers. Staining with H&E employs anchorable derivatives that can be cross-linked into the E×M hydrogel matrix.
