Xfold Imaging Oy is Aalto University spinout company. Xfold imaging produces signal-enhancing nanostructures for imaging and diagnostic applications. These structures can be produced on a variety of substrates, such as glass, polycarbonate, and silicon. The nanostructures enhance microscope images and optical signals obtained using laser/LED excitation, in the UV, visible or NIR range, and are compatible with fluorescence and label-free detection. Xfold imaging’s innovative solution enables the study of cellular structures and bio-molecules at enhanced accuracy and allows improved detection of weakly emitting particles, by enhancing the optical emission.
