Description

A kind of electric osmose Micropump device
Technical field
The utility model relates to microfluidic art, particularly relates to a kind of electric osmose Micropump device.
Background technology
Electric osmose Micropump is a kind of automatically controlled micro-fluidic driving pump based on EOF.When microfluid enters fluid channel in Micropump pump, runner wall solid-liquid interface place will form one deck electric double layer, when loading parallel electric field along fluid channel direction, fluid channel wall electric double layer occurs to shear migration and forms driven by electroosmosis power under electric field force effect, this driving force directly acts on neighbouring microfluid, drive it to flow, form EOF.Owing to having, drive fluid scope is wide, the continuous pulse free that flows, mechanical moving component, the large high-voltage performance of flow is good, reliability is high, long service life, and the feature such as the accurate control of rate of flow of fluid or pump pressure and the bidirectional modulation of the flow direction can be realized by electric operating, electric osmose Micropump gets the attention in micro-fluidic field, at present microfluid (buffer solution, pharmaceutical agent, suspension etc.) sample introduction transports, micro-move device actuator (microring array, microfocus, differential from etc.), there is embody rule in the micro-fluidic field such as microelectronic chip cooling.
Conventional electric osmose Micropump many employings solid metallic makes electrode, and electrode is arranged in pump and directly contacts with microfluid near fluid channel, produces under voltage and drives electric field.Directly contacting with fluid, easily there is hydrolysis and produces bubble, hydrolysising by-product, Joule heat etc. in electrode on surface.Along with the carrying out of hydrolysis, bubble and hydrolysising by-product can be collected at electrode surface gradually and reduce on-load voltage effective rate of utilization, even can flow to fluid channel and block electrokinetic flow.Although adopt inertia platinum or gold electrode can weaken hydrolysis to a certain extent, but still cannot thoroughly eliminate.
Current solution to the problems described above utilizes gel-type polymeric film to drive fluid channel to carry out physics at solid metallic electrode and pump electroendosmosis to separate.Solid metallic electrode is immersed in the lysis buffer of gel film side, keeps electrical contact by lysis buffer and gel film, and driven by electroosmosis fluid channel is then direct carries out electrical contact by microfluid and gel film.This gel-like material requires to have good conduction and water resistance, effectively can avoid the direct electrical contact of metal electrode and fluid channel electroendosmosis fluid, and the flowing of protection fluid channel electroendosmosis makes it not by electrode surface hydrolysis reaction interference.
In electric osmose Micropump running, when surface of metal electrode generation hydrolysis produces bubble, the gel film be arranged between metal electrode and fluid channel can stop bubble completely, hydrolysising by-product flows to interference driven by electroosmosis in fluid channel, thus makes EOF maintain constant flow.
Although said mechanism can reduce metal electrode hydrolysis to the impact of electric osmose fluid channel inner fluid flowing, but because solid metallic electrode still needs to contact with the lysis buffer of gel film side, therefore still can there is hydrolysis in electrode surface, produce bubble and hydrolysate, although the flowing of electric osmose fluid channel inner fluid can not be affected, but can have an impact to driving voltage, therefore, usually need arrange exhaust component at ate electrode drains into outside pump by bubble, pump body structure will be made so more complicated, and manufacturing cost also can increase.Other hydrolysate dissolved in a fluid then cannot be discharged.
