Abstract
The invention discloses a liquid suspension microstructure and a preparation method thereof. The liquid suspension microstructure consists of quartz or glass microneedles in parallel arrangement, the tip end of a microneedle array forms a concave face, and the other end of the microneedle array is hermetically sealed on a sleeve while an opening is reserved for inflation. The preparation method includes the steps: acquiring the microneedle array with the tip end being the concave face according to a method introduced in the patent ZL200710134575.2; and (2), setting up sealing and inflating devices at one non-microneedle end of the array. The liquid suspension microstructure and the preparation method thereof are novel in structure and can be applied to the fields of micro-nano preparation, sensing, optics, biomedicine and the like.
Description
Technical field
The present invention relates to the preparation method of a kind of nanometer and micron order fine structure material, particularly a kind of liquid suspension micro-structural and preparation method thereof.
Background technology
The preparation of liquid suspension micro-structural is a technology with important application background.Because there is the micro-nano hole between the microneedle array, and the tip of microneedle array formation concave surface, when an other end is filled with gas, will form the air supporting layer at the microneedle array tip.The pressure of air supporting layer is along with reduce the plane decision that its isobaric plane is formed by the microneedle array tip away from the micropin tip.When small fluid drips at the isobaric air supporting layer of concave shape, then drop can suspend.This special pattern and character have been given its special function and application.For example, owing to only have gas around the drop that suspends, do not exist and the interface of solid phase on every side, therefore can study some chemical reaction to get rid of effect of the interface; Can control the component and the concentration that are filled with gas, process and the mechanism of specializes in chemistry reaction; The nano particle that can prepare some special appearance and size.
Summary of the invention
The purpose of this invention is to provide the low liquid suspension micro-structural of a kind of preparation cost.Another object of the present invention provides the preparation method of this liquid suspension micro-structural.
In order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
Liquid suspension micro-structural, diameter are 200nm to 1000 micron quartz or the glass micropipette composition that is arranged in parallel, and the tip of microneedle array forms concave surface, and the bottom of microneedle array is enclosed on the sleeve pipe sealing and stays an opening so that inflation.
The preparation method of liquid suspension micro-structural of the present invention may further comprise the steps:
(1) the method acquisition tip according to patent ZL200710134575.2 is the microneedle array of concave surface;
(2) by being bonded and sealed or rubber interlayer sealing, or above method any combination makes up sealing and the aerating device of being made by metal, glass, pottery or plastic material in the bottom of microneedle array.
The present invention compared with prior art, its remarkable advantage is: (1) can obtain novel liquid suspension micro-structural; (2) with low cost, need not large-scale instrument, simple and reliable process.

The specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
The tip is that the microneedle array of concave surface is according to the method acquisition of patent ZL200710134575.2 among the embodiment.
Embodiment 1: the tip that the quartz fibre of preparation diameter 200nm consists of is the microneedle array of concave surface, then by 504 glue glass tube is bonded to non-micropin one end of microneedle array, namely forms the liquid suspension micro-structural.
Embodiment 2: the tip that the glass fibre of 3 microns of diameters of preparation consists of is the microneedle array of concave surface, then by the rubber interlayer copper pipe is fixed to non-micropin one end of microneedle array, namely forms the liquid suspension micro-structural.
Embodiment 3: the tip that the glass fibre of 1000 microns of diameters of preparation consists of is the microneedle array of concave surface, then by silicon rubber pvc pipe is bonded to non-micropin one end of microneedle array, namely forms the liquid suspension micro-structural.
Embodiment 4: the tip that the quartz glass fibre of preparation diameter 150 consists of is the microneedle array of concave surface, then seals non-micropin one end that glass tube is bonded to microneedle array by the rubber interlayer, namely forms the liquid suspension micro-structural.
