摘要： The use of optical micro cavities, high-Q resonators and slow-light structures as tools for detecting molecules and probing conformations and measuring polarizability and anisotropy of molecules and molecular assemblies using a pump-probe approach is described. Resonances are excited simultaneously or sequentially with pump and probe beams coupled to the same microcavity, so that a pump beam wavelength can be chosen to interact with molecules adsorbed to the microcavity surface, whereas a probe beam wavelength can be chosen to non-invasively measure pump-induced perturbations. The induced perturbations are manifest due to changes of resonance conditions and measured from changes in transfer characteristics or from changes of the scattering spectra of a micocavity-waveguide system. The perturbations induced by the pump beam may be due to polarizability changes, changes in molecular conformation, breakage or formation of chemical bonds, triggering of excited states, and formation of new chemical species. Furthermore, heat may be generated due to absorption of the pump beam. Furthermore, the use resonant modes with different states of polarization allows for measurements of polarizability and its anisotropy in samples interacting with the optical device.

摘要： The present invention relates to a microfluidic device for extracting and isolating DNA from cells. The device includes a support having an inlet port for receiving a sample containing a cell, an outlet port for dispensing DNA isolated from the cell, and a microfluidic channel disposed within the support and extending from the inlet port to the outlet port. The microfluidic channel includes a micropillar array, an inflow channel disposed between the inlet port and the micropillar array, and an outflow channel disposed between the micropillar array and the outlet port. The micropillar array includes micropillars spatially configured to entrap, by size exclusion, the cell, to immobilize DNA released from the cell, and to maintain the immobilized DNA in elongated or non-elongated form when hydrodynamic force is applied to the microfluidic channel. Systems and methods of making and using the device are also provided herein.

摘要： A device for use in luminescent imaging. The device can include an array of imaging pixels, and a photonic structure disposed over the array of imaging pixels. The device further can include an array of features disposed over the photonic structure. A first feature of the array of features can be disposed over a first pixel of the array of imaging pixels, and a second feature of the array of features can be disposed over the first pixel and spatially displaced from the first feature. A first luminophore can be disposed within or over the first feature, and a second luminophore can be disposed within or over the second feature. The device further can include a radiation source configured to generate first photons having a first characteristic at a first time, and configured to generate second photons having a second characteristic at a second time. The second characteristic can be different than the first characteristic, and the second time can be different than the first time. The first pixel can selectively receive luminescence emitted by the first luminophore responsive to the first photons at the first time, and can selectively receive luminescence emitted by the second luminophore responsive to the second photons at the second time.
