We report an experimental demonstration of a nonclassical imaging mechanism with super-resolving power beyond the Rayleigh limit. When the classical image is completely blurred out due to the use of a small imaging lens, by taking advantage of the intensity fluctuation correlation of thermal light, the demonstrated camera recovered the image of the resolution testing gauge. This method could be adapted to long distance imaging, such as satellite imaging, which requires large diameter camera lenses to achieve high image resolution.

Fluorescence fluctuation spectroscopy experiments were conducted to better understand the complex mass transport dynamics of organic molecules in liquid-filled nanoporous media. Anodic aluminum oxide (AAO) membranes incorporating 10 and 20 nm diameter cylindrical pores were employed as model materials. Nile red (NR) dye was used as a fluorescent tracer.

Acute intermittent porphyria (AIP) is a rare inherited metabolic disorder caused by decreased activity of the enzyme porphobilinogen deaminase in the heme synthesis pathway. This leads to the accumulation of toxic porphyrin precursors, such as porphobilinogen and δ-aminolevulinic acid. Clinical manifestations typically include episodic bouts of severe neurovisceral pain and autonomic dysfunction.
