Patent number: 10408824Abstract: Fluidic connectors, methods, and devices for performing analyses (e.g., immunoassays) in microfluidic systems are provided. In some embodiments, a fluidic connector having a fluid path is used to connect two independent channels formed in a substrate so as to allow fluid communication between the two independent channels. One or both of the independent channels may be pre-filled with reagents (e.g., antibody solutions, washing buffers and amplification reagents), which can be used to perform the analysis. These reagents may be stored in the channels of the substrate for long periods amounts of time (e.g., 1 year) prior to use.Type: GrantFiled: November 24, 2015Date of Patent: September 10, 2019Assignee: OPKO Diagnostics, LLCInventors: Vincent Linder, David Steinmiller, Samuel K.

Patent number: 10279345Abstract: Fluidic devices and methods involving incubation and/or mixing of assay components are provided. In some embodiments, a biological and/or chemical assay may be performed in a fluidic device. The fluidic device may be designed to allow for controlled incubation and/or mixing of two or more assay components. In some such embodiments, the fluidic device may include an incubation channel having a relatively large cross-sectional dimension in fluid communication with a detection channel. The incubation channel may allow for adequate mixing and/or incubation of two or more assay components prior to analysis of the assay. In certain embodiments, the detection channel may be used to provide feedback on the extent of incubation and/or mixing. Based on the feedback, one or more component of the fluidic system may be regulated to allow the requisite degree of mixing and/or incubation to be achieved.Type: GrantFiled: December 11, 2015Date of Patent: May 7, 2019Assignee: OPKO Diagnostics, LLCInventors: Matthew Dirckx, Jason Taylor, Vincent Linder

Publication number: 20180236448Abstract: Systems and methods for controlling fluids in microfluidic systems are generally described. In some embodiments, control of fluids involves the use of feedback from one or more processes or events taking place in the microfluidic system. For instance, a detector may detect one or more fluids at a measurement zone of a microfluidic system and one or more signals, or a pattern of signals, may be generated corresponding to the fluid(s). In some cases, the signal or pattern of signals may correspond to an intensity, a duration, a position in time relative to a second position in time or relative to another process, and/or an average time period between events. Using this data, a control system may determine whether to modulate subsequent fluid flow in the microfluidic system. In some embodiments, these and other methods can be used to conduct quality control to determine abnormalities in operation of the microfluidic system.Type: ApplicationFiled: April 19, 2018Publication date: August 23, 2018Applicant: OPKO Diagnostics, LLCInventors: Vincent Linder, David Steinmiller

Publication number: 20180099272Abstract: Fluidic devices and methods including those that provide storage and/or facilitate fluid handling of reagents are provided. Fluidic devices described herein may include channel segments positioned on two sides of an article, optionally connected by an intervening channel passing through the article. The channel segments may be used to store reagents in the device prior to first use by an end user. The stored reagents may include fluid plugs positioned in linear order so that during use, as fluids flow to a reaction site, they are delivered in a predetermined sequence. The specific geometries of the channel segments and the positions of the channel segments within the fluidic devices described herein may allow fluid reagents to be stored for extended periods of time without mixing, even during routine handling of the devices such as during shipping of the devices, and when the devices are subjected to physical shock or vibration.Type: ApplicationFiled: December 13, 2017Publication date: April 12, 2018Applicant: OPKO Diagnostics, LLCInventors: Jason Taylor, Vincent Linder

Publication number: 20180085753Abstract: Fluidic systems and methods for analyses are provided. In some embodiments, systems and methods for improved measurement of absorbance/transmission through fluidic systems are described. Specifically, in one set of embodiments, optical elements are fabricated on one side of a transparent fluidic device opposite a series of fluidic channels. The optical elements may guide incident light passing through the device such that most of the light is dispersed away from specific areas of the device, such as intervening portions between the fluidic channels. By decreasing the amount of light incident upon these intervening portions, the amount of noise in the detection signal can be decreased when using certain optical detection systems.Type: ApplicationFiled: October 18, 2017Publication date: March 29, 2018Applicant: OPKO Diagnostics, LLCInventors: David Steinmiller, Vincent Linder

Publication number: 20180078938Abstract: The specification generally discloses systems and methods for mixing and delivering fluids in microfluidic systems. The fluids can contain, in some embodiments reagents that can participate in one or more chemical or biological reactions. Some embodiments relate to systems and methods employing one or more vent valves to controllably flow and/or mix portions of fluid within the microfluidic system. Advantageously, fluid control such as a sequence of fluid flow and/or a change in flow rate, can be achieved by opening and closing one or more vent valves and by applying a single source of fluid flow (e.g., a vacuum) operated at a substantially constant pressure. This can simplify the operation and use of the device by an intended user.Type: ApplicationFiled: December 1, 2017Publication date: March 22, 2018Applicant: OPKO Diagnostics, LLCInventors: Enqing Tan, Vincent Linder, Jason Taylor, David Steinmiller

Publication number: 20170367783Abstract: Articles and methods for preparing a surface for obtaining a patient sample, such as blood, are generally provided. In some embodiments, the methods involve wiping a surface of skin of a patient in preparation for obtaining a sample (e.g., a blood sample) from the patient. In some embodiments, the methods involve wiping the surface of the skin with two or more wipes. For instance, the surface of the skin may be wiped with a first wipe comprising a surfactant and a second wipe comprising an antiseptic solution. Advantageously, the use of a first wipe including a surfactant followed by a second wipe may remove a higher amount of certain contaminants (e.g., proteins, bacteria, viruses) from the surface of the skin as compared to the use of a single wipe or by hand-washing alone.Type: ApplicationFiled: October 13, 2016Publication date: December 28, 2017Applicant: OPKO Diagnostics, LLCInventors: Jason Taylor, David Steinmiller, Hardeep Singh, Rebecca Wagner, Gary J.
