A method for detecting labile zinc (Zn.sup.2+) in a biological material is provided herein, the method including: (a) contacting the biological material with a composition including NapBu-BPEA; and (b) imaging the biological material via molecular fluorescence imaging to detect the labile zinc in the biological material. Also provided herein are methods for morphology-correlated detection of labile zinc localization in a subcellular organelle of a living cell and methods for tracking a change in labile zinc localization in a biological material.

Techniques for performing an acoustic rheology measurement of a sample are provided. A first set of acoustic pulses is provided by a focused ultrasound transducer to induce surface oscillations of the sample. A second set of acoustic pulses is provided by a detection transducer to interrogate the sample and detect the echo pulses reflected by the sample surface as a function of time. The detection ultrasound transducer system converts the echo signals to an electrical signal associated with the detected echo pulses, and a processor determines a dynamic displacement of the interface of the sample as a function of time. The processor also determines the spectrum, resonant surface oscillation frequency, and damping coefficient. Viscoelastic properties of the material are determined from these measurements, with applications for the characterization of the blood clotting process, the identification of a blood clot, gelation process, tumor, or fibrosis based on the viscoelastic properties.

A method of synthesizing an oligonucleotide using a nanofluidic device including a plurality of nanopore channels, a plurality of electrodes, and an electrolyte solution, includes coupling a primer to an inner wall of a nanopore channel of the plurality of nanopore channels, the primer having a protecting group. The method also includes applying a voltage to an electrode of the plurality of electrodes that corresponds to the nanopore channel to produce an acid from the electrolyte solution at the electrode. The electrode includes an anode and a cathode disposed at opposite sides of the nanopore channel. The method further includes the acid removing the protecting group from the primer. Moreover, the method includes coupling a nucleotide to the primer with the protecting group removed to form an intermediate product. In addition, the method includes repeating the steps on the intermediate product until the oligonucleotide is synthesized.

An apparatus is provided for sensing a molecule in a sample. The apparatus utilizes an electric field to draw molecules from a first chamber through an aperture, defined by a chemical layer, into a second chamber. The apparatus can detect a DNA molecule with, for example, 4, 5, or 6 unique base pairs. As molecules pass through the aperture, a sensor detects or measures a change in an electric parameter used to generate the electric field, thereafter translating the change in the electric parameter into information about the molecule. A divider element separates the first and second chambers and supports a chemical layer defining the aperture. The apparatus enables detection or measurement of molecules over prolonged time at a higher electric field strength than other nanopores, due to a combination of the shape of the divider, structural elements thereon, and thickness of the chemical layer at the aperture.
