Separation and detection of spermatozoa
InactiveUS6391654B1Reduce exerciseAvoid flowImmobilised enzymesApparatus sterilizationTransport mediumBiological activation
A kit for testing male fertility comprises a vessel, a base unit, a liquid supply containing liquid and two filters. The first filter is a sample separation filter which forms a hindrance to transmission of spermatozoa. The second filter of the kit is a spermatozoa detection filter comprising a reagent for identifying spermatozoa. Activation of the kit is prevented until a transport medium, such as the liquid, fills a gap allowing spermatozoa to transmit to a detection zone. The kit may be of one-piece construction and utilizes a thin piece of filter material to separate motile from non-motile spermatozoa.

Device (10, 110) for separating motile sperm from a sample (100, 200), comprises a vessel (15, 115) having an inlet port (20, 120), an outlet port (35, 135) which is initially closed, a medium (40, 140) into which motile sperm in the sample (100, 200) can migrate into the vessel (15, 115) via the inlet (20, 120), and an actuator (50, 150), the operation of which opens the outlet (35, 135), thereby allowing the medium (40, 140) to flow out of the vessel (15, 115) through the outlet (35, 135). The medium (40, 140) in the vessel (15, 115) is initially prevented from flowing through the outlet (35, 135), thus allowing an incubation period which allows motile sperm sufficient time to migrate from the sample (100, 200) into the medium (40, 140) before the medium (40, 140) leaves the vessel (35, 135). The device (10, 110) preferably comprises a spermatozoa detector in communication with the outlet. In devices for separating sperm, capillary flow takes place through non-fibrous material, such as the space between sheets (81a and 81b; 181a and 181b) of closely-juxtaposed material. A device for separating motile and non-motile sperm includes a temperature sensor, a heat source (70, 170) and, optionally, a temperature regulator.

Process For Sorting Motile Particles From Lesser-Motile Particles And Apparatus Suitable Therefor
Motile particles are sorted from non-motile particles in a microfluidic sorting device wherein a stream of sort fluid containing motile and non-motile particles is caused to flow adjacent a media stream in non-turbulent fashion through a sort channel, during which flow motile particles cross the interface between the adjacent flow streams, entering the media stream, and forming a motile particle-depleted sort stream. The sorting devices are easily and inexpensively fabricated and have numerous uses, in particular sorting of motile from non-motile sperm.

Optical cell guidance method and apparatus
InactiveUS7435568B2Bioreactor/fermenter combinationsBiological substance pretreatmentsLeading edgeDielectric
Embodiments of the invention include Optical Cell Guidance (OCG) methods and apparatus to control cell growth. This system guides the leading edge of motile cells with an optical gradient, which biases the cell's motion into the light by pulling on proteins, which act like soft dielectrics in the electromagnetic field. OCG differs from those devices described above in that it controls the direction of cell motility. This is an entirely new field, and the first device to directly manipulate cell motility. OCG differs from current approaches in that it does not trap or hold particles. Instead of trapping and pulling the cell, the goal of OCG is to influence, direct, and control the growth of a growth cone.
