Abstract: A system for characterization of a single molecule or cell sample by directing a beam onto the sample to produce energy emanating from the sample. A periodic sample holder with through-pores containing the sample is positioned to receive the beam. At least one pore is provided in the sample holder for holding the sample. The energy emanating from the sample is detected by a detector. The sample holder can be used to study individual molecules, viruses, or cells by various techniques including x-ray diffraction, chemical analysis, optical or electron microscopy, or electrochemistry.

Abstract: Disclosed are nanometer to micron scale functionalized apertures constructed on a substrate made of glass, carbon, semiconductors or polymeric materials that allow for the real time detection of biological materials or chemical moieties. Many apertures can exist on one substrate allowing for the simultaneous detection of numerous chemical and biological molecules. One embodiment features a macrocyclic ring attached to cross-linkers, wherein the macrocyclic ring has a biological or chemical probe extending through the aperture. Another embodiment achieves functionalization by attaching chemical or biological anchors directly to the walls of the apertures via cross-linkers.
