Abstract
This utility model relates to field of biosensors, is specifically related to a kind of CNT neuron electrode.It is characterized in that: described electrod-array adopts carbon nano-tube material, and array is arranged vertically above connecting frame.This utility model beneficial effect: carbon nano pipe array electrode is suitable as neuron electrode needs because it has outstanding toughness, electric conductivity and small size tip very much, change original array structure difficulty of processing large, hardness is high, incompatible shortcoming.
Description
Technical field
This utility model relates to field of biosensors, is specifically related to a kind of CNT neuron electrode.
Background technology
When analyzing neuronal cell and how completing various function, often need implantable neural unit electrode, its function obtains corresponding information feed back by different stimulating electrical signal brain districts.
At present, conventional nerve microelectrode has wire or planar structure, and material is made with metal material or silicon materials.Patent CN201410027692.9 or CN201110304586.7 devises the array electrode of unlike material respectively.
Above-mentioned material biocompatibility and made of soft degree poor, need a kind ofly there is good conductive capability, made of soft, changeableness and not the new material of easy fracture replace traditional electrode material.
Utility model content
The purpose of this utility model is to provide a kind of CNT neuron electrode, to overcome the deficiencies in the prior art.The appearance of carbon nano-tube material, meets above-mentioned technical characteristic, and has nano level tip and micron-sized length, meets process requirements simultaneously.
A kind of CNT neuron electrode, comprises electrod-array and connecting frame, it is characterized in that: described electrod-array adopts carbon nano-tube material, and array is arranged vertically above connecting frame.
Described CNT has certain support performance in vertical direction, can move with connecting frame, is therefore often used as the scanning needle point of atomic force microscope, and CNT toughness is strong, not frangibility.CNT also has excellent electric conductivity simultaneously.
Described connecting frame is used for fixing carbon nano pipe array and is connected power supply apparatus, can select metal material.
This utility model beneficial effect: carbon nano pipe array electrode is suitable as neuron electrode needs because it has outstanding toughness, electric conductivity and small size tip very much, change original array structure difficulty of processing large, hardness is high, incompatible shortcoming.
Accompanying drawing explanation
Fig. 1 is CNT neuron electrode structural chart
Detailed description of the invention
As shown in Figure 1, connecting frame 2 upper vertical growth electrod-array 1, electrod-array 1 adopts carbon nano-tube material, and carbon nano tube growth mode selects traditional CVD method.Laser ablation carbon nano pipe array, the electrod-array 1 of formation rule arrangement.
During electrod-array 1 pair of neuron electricity irritation, CNT small size tip can with neuronic shape, and self adjustment is done in position, thus the excitation realized neuron activity or suppression.
