We propose and demonstrate a compact, alignment-free dark-field microscopy technique, termed as organic light-emitting-diode-based plasmonic dark-field microscopy. Experimental results show that it is capable of forming dark-field images of the specimens utilizing a highly integrated chip-scale plasmonic condenser. This technique has high z resolution and high imaging contrast and is suitable for the dynamics study near the contact regions of living cells and the substrate.
