Problems solved by technology

[0015] However, although the former method for component analysis of drugs is accurate, it is complicated to implement, and it takes a lot of time and energy for ordinary people to identify drugs in this way.
Although the latter is convenient and fast, it only marks the packaging of the packaged medicines. If the counterfeit and inferior medicines are put into the regular packaging, then this method is powerless

Embodiment 1

[0078] Drug anti-counterfeiting can be achieved by using nano-diamonds containing nitrogen-vacancy centers, or by drawing nano-diamonds on the surface of drugs (these graphics can be pre-designed patterns, such as bar codes, two-dimensional codes, etc., or random graphics ), through the analysis of the graphic, the authenticity of the drug can be confirmed. Taking nanodiamonds as an example to draw random patterns on the surface of the drug, its anti-counterfeiting method can specifically include the following steps:

[0079] Step 1: Determine a certain area on the medicine as a safety marker area.

[0080] Step 2: Load the nanodiamond powder into the spray gun and spray NV on the drug - Nano-diamond powder forms random patterns made of fluorescent diamonds on the surface of the drug. The powder can be attached in various ways, for example, a layer of edible glue can be attached on the surface of the drug, and then NV nano-diamond powder can be sprayed.

[0081] Step 3: Irr...

Embodiment 2

[0087] Any one of the following two schemes can be adopted to realize the anti-counterfeiting of light-transmitting materials or articles (such as display screens, etc.) containing light-transmitting materials by using nano-diamonds containing nitrogen-vacancy centers:

[0088] Option One

[0089] This option can include the following steps:

[0090] Step 1: For an item composed of a certain type of transparent material or containing a part of light-transmitting material, generate its special marking graphic style (this image can contain the information of the transparent material or item, taking the display screen as an example, it can include such as the screen name, production date, code, hardness, etc.), and the graphic and the information it contains are stored in the server.

[0091] Step 2: During the production process of the transparent material or article, use a mask plate to spray nano-diamond powder or solution containing nitrogen-vacancy centers on a certain area...

Embodiment 3

[0101] Solution anti-counterfeiting by utilizing nanodiamonds containing nitrogen-vacancy centers can include the following steps:

[0102] Step 1: For a specific solution, design its special nanodiamond size and concentration (this size and concentration information can correspond to the name, formula, efficacy, etc. of the solution), and store the concentration and the information contained in it at the same time. in the server.

[0103] Step 2: Add specific size, quality nano-diamond powder (or specific concentration and volume of nano-diamond solution) to the solution in the process of solution bottling and packaging.

[0104] Step 3: Take the solution to be tested to make a sample, irradiate it with a 532nm laser, and use a filter and a light collection system to obtain the light signals emitted and reflected by the sample.

[0105] Step 4: By processing the obtained optical signal, the size and concentration of nano-diamonds in the sample are obtained, and compared with...

Abstract

The invention discloses a nano-diamond-based anti-counterfeiting method, a corresponding medicine, anti-counterfeiting ink and an application thereof. The nano-diamond-based anti-counterfeiting methodcomprises: coating the surface of the article to be subjected to anti-counterfeiting treatment with nano-diamond particles or adding nano-diamond particles into the article to be subjected to anti-counterfeiting treatment. The nano-diamond particle contains nitrogen-vacancy center NV<-> in a negatively charged state and produces fluorescence emitted by the excitation light at the wavelength of 400 nm to 600 nm so that anti-counterfeiting effects are obtained. Under control of the internal structure of the key nano-diamond material, through fluorescence produced by the nano-diamond material containing nitrogen-vacancy center NV<-> in a negatively charged state under excitation light at the wavelength of 400 nm to 600 nm, the anti-counterfeiting effects are effectively achieved.

Description

technical field [0001] The present invention belongs to the technical field of anti-counterfeiting, and more specifically relates to an anti-counterfeiting method based on nano-diamonds, corresponding medicines, anti-counterfeiting inks and applications thereof. and anti-counterfeiting medicines. Background technique [0002] Conventional anti-counterfeiting inks mainly fall into the following categories: ultraviolet fluorescent inks, sunlight-induced color-changing inks, infrared anti-counterfeiting inks, heat-sensitive anti-counterfeiting inks, pressure-sensitive anti-counterfeiting inks, magnetic anti-counterfeiting inks, optically variable anti-counterfeiting inks, and anti-alteration anti-counterfeiting inks. Ultraviolet fluorescent inks, sunlight-excited color-changing inks, and infrared anti-counterfeiting inks (these three inks are collectively referred to as color-changing inks below) are all inks that emit visible light under light irradiation. The light correspond...
