Description
Technical field
The present invention relates to a kind of design of reaction pool device, specially a kind of reaction pool devices based on micro-cantilever.
Background technique
Micro-cantilever is one of simplest MEMS device, and constructs the basic unit of other complicated MEMS device.Its
Size is very small, has many advantages, such as that high sensitivity, effect are strong.Micro-cantilever beam sensor can be used for detecting macromolecular, such as
Detect the concentration of antigen-antibody in the speed and body fluid of Polymer adsorption.It is closed so to design one kind, it is simply, anti-for liquid
The container answered then becomes a committed step.Existing reaction tank container joint is excessively complicated in the world at present and is mostly quartz
It is made Deng material costly.Therefore, it is necessary to design a kind of simple, reliable and cheap reaction pool device, this hair
Bright place in order to avoid the shortcomings of the prior art, provides a kind of reaction pool device based on micro-cantilever beam sensor,
In the device, micro-cantilever clamping device and reaction tank matrix are separate type, avoid and are placing micro- hang because reaction pool size is small
Existing trouble when arm beam.By rubber ring, transparent glass sheet and metal cover board create the environment being completely closed.
In document " micro-cantilever biochemical sensor development and detection application ", the micro-cantilever reaction tank that author proposes is pressed from both sides
It holds and is structure as a whole with reaction tank matrix, place micro-cantilever operating difficulties, be easy to damage and airtightness is poor.
In document " Influence of Fluid Cell Design on the Frequency Response of
AFM Microcantilevers in Liquid Media " in, the reaction tank of author designed is made of quartz, and price is extremely
Valuableness, and it is exposed in external environment to be retained as a thin wire, easily snaps off.
Summary of the invention
The present invention in order to avoid the shortcomings of the prior art place, provide it is a kind of based on micro-cantilever reaction tank dress
It sets, in the apparatus, micro-cantilever clamping device and reaction tank matrix are separate type, are avoided because pool size is small is placing for reaction
Existing trouble when micro-cantilever.By rubber ring, transparent glass sheet and metal cover board create the environment being completely closed.
This solution technical problem adopts the following technical scheme that
One detachable micro-cantilever clamping device is made of spring, inserted metal loop bar and clamping matrix；
One reaction tank matrix, the matrix are made of the stainless steel of a rectangular block shape, and reaction tank internal structure is by solution groove
It is formed with micro-cantilever clamp groove, there is the groove of a placement rubber ring and metal cover board, table on reaction tank above solution groove
There are four screw holes in face, are finally fixed up with a metal cover board and screw, constitute closed environment.
The micro-cantilever clamping device usage mode is to be pulled outward to stretch end with a hand, so that press beam end is the same as micro- outstanding
Then the separation of arm beam notch places micro-cantilever with another hand and finally unclamps hand, micro-cantilever is just clamped by stable.
It is recessed that the solution groove horizontal plane outline of the reaction tank intrinsic silicon is higher than the micro-cantilever clamping come round therewith
Slot avoids shaking reaction tank that clamping device is fallen off, and micro-cantilever clamp groove height is higher than micro-cantilever clamping dress
Set, make micro-cantilever clamping device completely into reaction tank inside, reaction tank matrix or so respectively the entrance comprising a solution and
One outlet.
Compared with the prior art, the invention has the advantages that:
1. micro-cantilever clamping device of the present invention is detachable disconnected from each other with reaction tank matrix, so that micro- outstanding placing
The fault that arm beam avoids manual operation causes the damage of micro-cantilever；
2. the present invention is integrated with stainless steel metal and is made, at low cost, can come into operation extensively；
3. the present invention is created for the detection of liquids and gases by rubber ring, transparent glass sheet and metal plate and is completely closed
Environment so that the disengaging of liquid it is unobstructed smoothly.
