The invention relates to a process and a device for analysing single molecules, particularly to the parallel analysis of a plurality of single molecules. It is suitable for detecting interactions, e.g. binding between single molecules and/or reactions, e.g. elongation or degradation of single molecules. Particularly, the process of the invention relates to the sequencing of single nucleic acid molecules. The single molecule to be analysed is present in free form, i.e. dissolved or suspended in a liquid medium, within a reaction space formed around the sample spot. According to the present invention, an electrical field is applied across the reaction space, whereby a concentration of single molecules, at the sample spots is effected.

Systems, devices, and methods for rheological measurement of yield stress fluids using fractal-like fixtures

The present disclosure is directed to rheometric fixtures for making rheological measurements of yield stress fluids. In some embodiments, the fixture can be an improvement of a typical vane by having the ability to create a more homogeneous shear profile in a test material, e.g., a yield stress fluid. These vane fixtures having fractal-like cross-sectional structures enable robust rheological measurements of the properties of yield stress fluids due to several outer contact edges that lead to increased kinematic homogeneity at the point of yielding and beyond. The branching structure of the fractal-like fixtures can alter the shape of a wetted perimeter of the fixture while minimizing an area thereof to allow the fixture to be inserted into fluids with less disturbance. In some embodiments, a cup with a ribbed inner surface can be used to hold the sample fluid and disassembles for ease of cleaning following completion of the measurement.

The system is configured for loading single cells into the microarray and for flowing cell lysis buffers and other reagents into the microarray for performing RNA library sample preparation. The system is also configured for lowing optical hybridization probes that are complementary to the cell identifying optical barcodes and optically labeled onto the microwell array and for obtaining images of the microwells in response to the probes. The system and unique cell identifying optical barcodes and complementary optical hybridization probes facilitate a link between phenotypic imaging of cells resident on the microwell array with single cell whole transcriptome sequencing.
