  • Publication number: 20170045427
    Abstract: Provided herein are methods and related systems for controlling droplet spreading on a surface, including droplets in which a biological component is suspended. A biological solution is provided as a droplet to a surface. Interference fringes generated by the droplet on the surface are imaged, wherein the imaging is over a time course during which the droplet spreads on the surface. A droplet parameter is determined from the imaging step and a process parameter controlled to obtain an interference fringe pattern corresponding to a desired droplet parameter. In this manner, well-controlled droplet spreading is achieved, which is important in a range of applications, including assays that rely on good metaphase spreading.

  • Patent number: 9409173
    Abstract: Provided herein are devices and methods for generating microfluidic gradients, including an array of unique microfluidic gradients within an array of microchannels. Fluids within conduits are mixed in an intersection region to generate a mixed flow stream in a source reservoir channel that provides a gradient that varies with axial distance from the intersection region. Microchannels having an inlet connected to the source reservoir channel are configured to provide a microfluidic gradient in the microchannel. An outlet end of the microchannel is connected to a sink reservoir channel. By varying the ratio of fluid flow rates from the fluid conduits, the microchannel gradients are tuned. In this manner, a large number of unique gradients or array of microfluidic gradients is provided, wherein the gradient can be any number of physical or chemical parameters, including concentrations and physical fluid properties.

  • Publication number: 20160168623
    Abstract: A method of analysing a sample includes providing a first part of the sample and a second part of the sample. A first analysis is conducted on the first part of the sample and the results of the first analysis are considered. A second analysis is conducted on the second part of the sample, the second analysis being conducted according to a procedure using a value for each of one or more characteristics of the procedure. The consideration of the results of the first analysis is used to determine whether the value for one or more of the characteristics of the procedure is changed to a different value. The second analysis is started before the results of the first analysis are obtained.

  • Publication number: 20150047413
    Abstract: A method of verifying the performance of a size standard, formed of a plurality of size standard elements, used in a nucleic acid analysis method is provided. The verification is achieved by introducing the size standard to an analysis stage and performing a size based separation on the size standard. The size based separation defines an experimental position for each size standard element. A comparison is made as to whether or not the experimental position for the size standard element corresponds with expected position. The comparison allows a decision to be made on whether or not to use the size standard, which is dependent upon whether or not the experimental position of the size standard element corresponds with the expected position.
