Description
Art
The new method that surface has the molecular blotting polymer microsphere of hydrophilic macromolecule brush is prepared the present invention relates to a kind of,
Specifically it is exactly to be related to a kind of new surface grafting method, surface can be obtained by this method has hydrophilic macromolecule
The molecular blotting polymer microsphere of brush.
Background technology
Molecular imprinting technology is a kind of new side for the simple and effective for preparing the polymeric acceptor with specific recognition site
Method, polymer therefrom is referred to as molecularly imprinted polymer (Molecularly imprinted polymers, MIPs).
MIPs not only has the advantages that excellent mechanical resistance energy, chemicals-resistant and heat resistance and easy preparation and cost are low, and
Also there is the high-affinity that can be compared favourably with natural biological acceptor and selectivity, thus SPE, chromatographic isolation, immune point
The various fields such as analysis, sensor, imitative enzymatic, organic synthesis, drug delivery and bio-pharmaceutical show huge application prospect,
Focus (Zhang, H. as current molecular recognition area research；Ye, L.；Mosbach, K.J. Mol.Recognit.2006,
19：248-259).
Although molecular engram research has achieved huge progress, in some application fields (such as solid phase extractions) MIPs even
The commercialization practical stage is entered, but the MIPs that people obtain at present generally could be to organic only in organic solution system
Small molecule shows excellent molecular recognition performance, and really suitable for water solution system using organic molecule as template
MIPs is then very limited.This greatly hinders practical applications of the MIPs in the field such as bionical immunoassay and sensor.
Recently, we have developed a series of preparations has hydrophilic macromolecule brush suitable for the surface of water solution system
The new method of MIP microballoons." two-step method " and " one-step method " approach can be divided into by being summed up." two-step method " approach is by sharp first
Preparing surface with controllable/" activity " free radical precipitation polymerization technology, there is controllable free-radical polymerisation to trigger or chain tra nsfer group
MIP microballoons, then again using it as immobilized initiator or chain-transferring agent, the surface controllable free-radical for carrying out hydrophilic monomer gathers
Close, obtaining surface has MIP microballoons (Pan, the G. of hydrophilic macromolecule brush；Zhang, Y.；Guo, X.；Li, C.；Zhang,
H.Biosens.Bioelectron.2010,26,976-982；Pan, G.；Ma, Y.；Zhang, Y.；Guo, X.；Li, C.；
Zhang, H.Soft Matter2011,7,8428-8439)." one-step method " approach be by large hydrophilic molecular chain-transferring agent (or
Macro RAFT agent) it is incorporated into reversible addition and fragmentation chain transfer (RAFT) precipitation polymerization system, one-step method is prepared suitable for pure
The surface of water solution system has MIP particles (Pan, the G. of hydrophilic macromolecule brush；Zhang, Y.；Ma, Y.；Li, C.；
Zhang, H.Angew.Chem.Int.Ed.2011,50,11731-11734；Ma, Y.；Pan, G.；Zhang, Y.；Guo, X.；
Zhang, H.Angew.Chem.Int.Ed.2013,53,1511-1514).Though above two preparation method, which can be prepared, is suitable to water
The surface of solution system has the MIP microballoons of hydrophilic macromolecule brush, but there is also respective shortcoming." one-step method " is due to must
Hydrophilic Macromolecular chain transfer agent must be added directly into molecular imprinting polymer system, this can be to function monomer and template point
Self assembly between son has a negative impact.In addition one-step method complex polymerization systems, cause the hydrophily of gained MIP microsphere surfaces high
The density of molecular brush can not be obtained, therefore limit the structural characterization of product；And " two-step method " approach prepare surface have it is hydrophilic
Property polymer brush MIP microballoons when, the molecular weight of the hydrophilic macromolecule brush that its surface is grafted is influenceed very big by reaction condition,
It is difficult the MIP microballoons for obtaining the hydrophilic macromolecule brush with identical molecular weight during duplication of production, so that product can be largely effected on
The stability of performance.In addition, the molecular weight that the method also has the hydrophilic macromolecule brush on gained MIP microballoons can not be determined directly
Difficulty.
The content of the invention
In terms of overcoming the shortcomings of that above method preparation surface has the MIP microballoons of hydrophilic macromolecule brush, the present invention
There is provided a kind of new preparation method, it is intended to which more prepare surface has the parent for determining molecular weight and grafting density simple and effective
