Description
Technical field
What the present invention relates to is a kind of method of field of nanometer technology, particularly a kind of based on the control method of glutathione to gold nanometer particle grain size.
Background technology
In recent years, along with the rise of nanosecond science and technology, the gold grain of nanoscale shows potential using value in a lot of fields with its unique optics, electrical properties, has caused the research interest that people are dense.The particle diameter of nano Au particle and size affect its potential application at aspects such as chemistry, biology, electronic devices strongly.When particle during less than 100nm, its optics, electricity and magnetism characteristic rely on particle size strongly, therefore by the particle diameter of control golden nanometer particle can be indirect obtain desired physical property.The control method of gold nanometer particle grain size has multiple, as liquid-phase extraction method, crystal seed method, electrochemical process etc.But the common operating procedure complexity of these methods, condition is wayward, the particle diameter wider distribution.
Find through literature search prior art, people such as calendar year 2001 Gen T are at " Japanese applicating physical magazine " (Jpn.J.Appl.Phys., 2001,40 (1) 346-349) delivered the article of " being dispersed in the golden nanometer particle of controllable size in the organic solvent " (Well-size-controlled Colloidal Gold NanoparticlesDispersed in Organic Solvents) on, this article adopts in the process of preparation aurosol and adds tannic acid, obtain the method for the gold nano grain of different-grain diameter by changing the volume that adds tannic acid, and will dissolve in the multiple organic solvent behind the aurosol solution centrifugal.This method is simple to operate, and the size that can control golden nanometer particle is between the 5-18 nanometer.But the prepared golden nanometer particle bio-compatibility of this method is relatively low, and the controlled dimensions scope of golden nanometer particle is narrower.
Summary of the invention
The objective of the invention is at deficiency of the prior art, provide a kind of based on the control method of glutathione to gold nanometer particle grain size, make it pass through the adding of glutathione, directly obtain the glutathione gold nano-particles modified, method is simple, practical, good, the uniform particle diameter of gained nanoparticulate dispersed, particle diameter can be controlled in the 8-40nm scope.
The present invention is achieved by the following technical solutions, and concrete steps of the present invention are as follows:
A. citric acid three sodium solution and glutathione solution are mixed.
B. solution and the chlorauric acid solution with gained among the step a heats respectively, mixes then.
C. after treating the solution changes color of gained among the step b, solution is heated to boiling, reacts fully, then the solution cooling is obtained the golden nanometer particle sol solution.
In step a, glutathione used in the present invention is oxidized form of glutathione or reduced glutathione.The mass ratio of glutathione and gold chloride is controlled to be (0.01-2): 1, because the glutathione of minute quantity is less to the influence of gold nanometer particle grain size, and after glutathione surpasses certain proportion, the gold chloride reduction rate slows down, grain diameter influence's effect to gold particle weakens, so the optimum quality ratio of glutathione and gold chloride is (0.1-0.8): 1.
In step b, in order to make the gold chloride Restore All, need to add excessive trisodium citrate, therefore the mass ratio of controlling trisodium citrate and gold chloride is greater than 1: 1, preferred proportion (3-4): 1, heating and temperature control is between 50-75 ℃.
In step c, the ebuillition of heated time is 5～20 minutes, is evenly distributed in order to make particle diameter, and sufficient reacting reduces the reunion of golden nanometer particle simultaneously, and Best Times is 8-15 minute, and the particle diameter of gained golden nanometer particle is 8-40nm.
The present invention utilizes trisodium citrate reduction gold chloride to obtain gold particle, in preparation process, directly add glutathione simultaneously, utilize the coating effect of glutathione, the particle diameter of control golden nanometer particle, and form modification and the dispersion of glutathione to the golden nanometer particle surface.
The present invention's employing adds glutathione and prepares the controlled golden nanometer particle of particle diameter in the golden nanometer particle preparation process.Can realize the modification of glutathione easily owing in course of reaction, directly add glutathione to golden nanometer particle.Method provided by the present invention has simple, efficient height, characteristics such as particle size is convenient adjustable, and bio-compatibility is good.The golden nanometer particle that makes thus can be applicable to DNA detection, biology and medicine and other fields, is easy to be extended and applied.
