Description
Technical field
The invention belongs to technical field of nano material, and in particular to it is a kind of it is through mercaptopyridine modification, have in infrared region
The oxide-based nanomaterial of the anti-plant decay disease of plasmon resonance property, preparation method and applications.
Background technique
The rot disease of plant is always to perplex a kind of common disease of peasant.Rot disease is also known as decay, bark rot, is fruit tree
A kind of common disease that class plant pole is also easy to produce, there is generation all over the world.
The fungi and bacterium that rot disease is mainly carried by several hundred kinds by soil cause, and it is corrupt to be characterized in that plant is disintegrated.It is rotten
It is can be hard, dry, spongiform or more water, congee gruel shape or stickiness.For root-rot caused by many fungies, root-rot is rotten simultaneously
It is covered with the black threadiness beam of mould layer.Foxiness is also to be invaded timber caused by fungi and often change colour or colour, soft corruption is frangible
It or is in powder mustiness.Rot disease ordinary loss is slow, often through for many years.It infects and nearly all occurs through wound.The shape of a hoof and layer frame shape
Entity is developed along limb, or forms bacterium gill fungus in butt or wound.Early stage is not easy to identify from appearance, raises limb
Epidermis, can see crineous to bronzing moisten stigma or isabelline dry spot, sometimes, internal lesion area is
It is larger but still not easy to identify from outside.Cortex is easily detached from after lesion, and rotten cortex is in bronzing, and there is vinasse taste in when web rot shape.
It falls ill the later period, sick portion's dehydration drying shrinkage becomes dark brown and sink, and generates dark brown dot grain, i.e. point of germ in top
Raw spore device, becomes the infection sources of recurrence.
Rot disease main harm limb fructiferous, treelet and nursery stock may also be encroached on, but it is less to fall ill.Because of morbidity
It is difficult to early period discover, so preventing and controlling are difficult to carry out.
It is existing prevention and treatment plant decay disease method spray insecticide antibiotic and sterilizing, rationally control plant spacing, cut in time
It cuts down morbidity limb, no matter any all time-consuming consumptive material and can not eradicate.The use of antimicrobial agent is to realize prevention and treatment plant decay
One of sick most efficient method.By adding the antibacterial agent that there are antibacterial functions and can be stabilized in a solvent, through certain work
After skill processing, the medicament with antibacterial and sterilizing function is made, it is not only free from environmental pollution, but also antibiotic and sterilizing can be kept for a long time
Effect.
Current main sterilization material can be divided into inorganic sterilization material and organic bactericide material.Due to consideration that environment and
Tissue safety has no toxic side effect and the problem of biocompatibility, inorganic sterilization material is relatively limited.Inorganic sterilization material
Metal ion type (silver, copper, zinc etc.) and oxide photocatalyst-type (titanium dioxide, zinc oxide, magnesia etc.) can be divided into, made
After nanoscale, specific surface area increases, and can preferably adsorb microorganism with good antibacterial effect.Metal ion type is inorganic
It is typically bactericidal nano-silver material in sterilization material, after the advantage is that thallus inactivation, Ag ion and therefrom separate out, weight
Multiple sterilization, effect is lasting, that is, has long-term effect.Be disadvantageous in that be easy discoloration and it is at high cost.The antibacterial effect light of Ag ion
Very big with the influence of heat, unstable, long-time service is easy to be reduced and reduce antibacterial effect.Oxide photocatalyst-type mainly with
TiO2To represent, it the advantage is that its chemical property is stable, anti-microbial property is wide, acid and alkali-resistance, nontoxic, raw material sources are abundant.Disadvantage
It is to be difficult to settle, is not easily recycled.More representational a few class organic bactericides are chitosan, flavone compound, antibiotic, season
Ammonium (phosphorus) salt and macromolecular bactericide.Its advantage is that good biocompatibility, at low cost, and it is nontoxic, there is good anti-microbial property.
The disadvantage is that poorly water-soluble, it is highly difficult to use it as additive, needs acidic environment.
In order to overcome existing antibacterial agent to be applied to the disadvantage in the prevention and treatment of plant decay disease, sight is now focused on into novel inorganic
Antibacterial agent makes it have outstanding advantage in all various aspects such as persistence, broad spectrum antibacterial and fast light heat resistance.
This patent has researched and developed a kind of novel inorganic antiseptic, includes the antimony-doped tin oxide modified through mercaptopyridine
(ATO), indium doping tin oxide (ITO), aluminium-doped zinc oxide (AZO), indium doping cadmium oxide (ICO) etc. have infrared phasmon
The nano material of resonance characteristics plays plant decay disease using infrared plasmon resonance characteristic and effectively prevents.
These materials have low cost of material, processing easy to produce, broad-spectrum antibacterial property height, light shine, few photoetch etc. excellent
Point.The experimental results showed that such anti-biotic material is with the mediation of infrared plasmon resonance characteristic or combination mercaptopyridine molecule
For Antibacterial Mechanism, inhibit spore germination and hyphal development.Currently, there is no relevant commodity circulation and reported literatures in the market.
Summary of the invention
Morbidity germ and environmental requirement for plant decay disease, the present invention provides a kind of to modify through mercaptopyridine
The nanometers such as antimony-doped tin oxide (ATO), indium doping tin oxide (ITO), aluminium-doped zinc oxide (AZO), indium doping cadmium oxide (ICO)
Preparation and application of the particle as antibacterial agent, this kind of material the surface of nanoparticle generate it is close, in infrared phasmon
Covibration.The present invention synthesizes and has studied a kind of novel inorganic antimicrobial agent, is with nanoparticles such as ATO, ITO, AZO, ICO
Main component is modified through mercaptopyridine, and other auxiliary agents are added, and novel anti-rot sick medicament is made using nanostructure characteristic, grinds
Study carefully the inhibiting effect after it is applied to plant decay disease.
For most of fungies, main Antibacterial Mechanism is to destroy cell tissue to inhibit germ sprouting and hyphal development.This
Class anti-biotic material Antibacterial Mechanism are as follows: due to the special level structure of nano material, under sunlight irradiation, ATO, ITO, AZO,
The nanoparticle surfaces such as ICO generate infrared plasmon resonance phenomenon, using the conversion of infrared light plasmon resonance energy, lead to
The protein for crossing the numerator mediated conversion of mercaptopyridine or directly conversion, generated energy and fungal cell and its spore is made
With, make cell cortex protein, lipid etc. and be activated, aoxidize and even destroy, further destroy its internal structure, while also inhibiting
Mycelium germination and growth, to reach antibacterial action.Meanwhile this kind of nano material has great specific surface area, is easier to and disease
The contact of bacterium occurrence of large-area is also conducive to clear up it.
The mass fraction of nanoparticle and germ action time are to antibacterial in the doping level of nanoparticle, antimicrobial agent
Rate has apparent influence.We by antimony-doped tin oxide (ATO), indium doping tin oxide (ITO), aluminium-doped zinc oxide (AZO),
The doping level of the synthetic method control nanoparticle of the nanoparticles powders such as indium doping cadmium oxide (ICO), by the way that sulfydryl pyrrole is added
