[Prior Art] The application of nanoparticle in imaging is used in the optical application part. Traditionally, (4) optical molecules including fluorescent organic molecules, laurel proteins, etc. 'The benefits of organic molecules are small, and the secrets are decorated' and after the exhibition in Nagasaki Many molecules with strong luminosity and stable light emission have been produced, mostly applied to antibodies; fluorescent proteins require a large number of genetic engineering operations' but can be beneficial for the observation of protein interaction studies. Recently, many nanoparticles have been found to have filaments, such as quantum dots, which can produce different wavelengths of fluorescence. The molecular absorption coefficient is high, and the peak width of the radiation is narrow, so that multicolor dyeing can be achieved. And the phenomenon of photobleaching is not much more obvious than the traditional materials. It can be used for long-term observation, and it can also be used as a new-generational cursor. The cage gold or silver na[iota] can be detected by surface plasma resonance. A few reports are using its fluorescent light. In the nuclear magnetic resonance imaging technique, the nanoparticles are different according to their TI retardation and T2 retardation, and the 'iron oxide Τ2 is slow and short, so the Τ2 slow measurement can be 1342787 to produce obvious Contrast. In addition, the biolipid particles of the microlipids have excellent applications in ultrasonic imaging. However, the toxicity problem of nanoparticle in vivo is also the focus of current research. Because the silk of the present is often used to change the material, the golden age of the activated material is quite active, so that it can be biomolecules in vivo. Interaction _, causing considerable toxicity. Therefore, lipid-based secrets can be used to reduce non-specific binding and unnecessary toxicity. The development of Φ frequency doubling technology uses the technology of the fluorescent cursor to understand the interaction of the microscopic or macroscopic world of the organism has been widely used in various biological fields. Therefore, the existence of optical, fluorescent or total focus microscopy is already In biological experiments, it is impossible to obtain a lack of equipment. However, the county standard has a fatal flaw. Once the fluorescent substance is excited, the energy may be released, and the sample itself may be harmed. Light irradiation causes the length of the co-consumption of molecules to change, leading to photobleaching, which is even more disturbing for researchers. However, the frequency doubling technology does not involve fluorescence, and the energy does not accumulate and the sample is not damaged. Therefore, it has become a novel optical technology in the world in recent years. Among them, the double frequency signal comes from the neatly arranged nanometer. The crystal structure is graded, while the triple frequency is derived from the discontinuous interface. The signal fat ball detected by the frequency doubling technique can produce an oil-water interface when suspended in an aqueous solution, so three frequency codes can be generated, but the optical signal is affected by the particle size. Only fat balls larger than 400 nm can be used. Producing a identifiable signal, the signal intensity of a fat globule larger than 1 micron is good for analysis, while for less than 4 〇〇 nanometer, the 1342787 signal is weakly. Therefore, this method can only be applied to fat cells or tissues that produce a large amount of fat. , • Signals of metal under frequency doubling technology, · Several metals or alloys are known to produce triple frequency signals, such as gold, silver, iron alloys, etc. However, 'signals are not strong, generally, gold, silver, etc. The metal itself has the effect of surface resonance, which can be excited by the laser to generate a double or triple frequency signal, but the signal strength is not high, and a fairly sensitive recorder is needed to capture the correct signal. In contrast, lipid is a kind of The biopolymer, which is arranged by the laser source, can also generate a triple-frequency signal itself, but similarly, its signal is quite weak, and the signal-to-noise ratio is not good, even with a good recorder record. The image is also quite blurry. The lipid nanoparticle disclosed in the present invention, the coated nanoparticle material, whether metal or non-metal, can generate a signal intensity greater than ten to one hundred times of the individual monomer signals (as shown in the figure of the present invention) Ten, _), the clarity of the image, so that the fat f nanoparticle becomes a development contrast agent for instant images. • [Summary of the Invention] The nano biotechnology disclosed in the present invention mainly utilizes metal particles or non-metal materials with a diameter of less than two hundred nanometers, and is a nutrient-rich nutrient. The rice particler can use the appropriate surface modification to efficiently deliver the drug molecules carried to the surface or body of the living organism cell, and can simultaneously serve as an image of multimodaUty imaging. Contrast agents, to simultaneously observe the mechanism of immediate action of drugs' or to understand the molecular basis of the cause of the disease. 1342787 This technology combines the benefits of both lipids and metals to construct metal or non-metallic lipid nanoparticles. It has been found that nanospheres above 50 nm can produce clearly identifiable triple-frequency signals. The rice particle signal is stronger, and the intensity of 100 nm or more is not obviously enhanced, but it can clearly determine the change of the size of the chick, and observe the secret reaction between the molecules in the cell, so 5 confirm this kind of nai Rice ball can be used as a three-frequency technology in vitro (invitr〇) or in vivo (inviv〇) developer (contrast agent) 〇 / butyl, rice particles have been used in the application of organisms for many years, can be used for drug carrying , called "gene delivery. However, if the nanoparticle is too large (>Chenna), the organism will recognize it, and after the reticuloendothelial resection in the living body, the short-term will accumulate in the liver, kidney, etc., causing non-specific toxicity, or Producing background noise can cause the image to be stunned. Since there is inherently fat in the living body, the toxicity is small, and the biocompatibility is high, and it is used for the packing of the nanoparticles to reduce the toxicity of the nanoparticles. Xiangzheng valence lipid and polyethylene glycol (PEG) modified lipid f self-assembly (four) f_assemb丨ed) principle, adjust the ratio of the two (such as Table 1, Table 2), or add neutral lipids (such as Table 3 And through the ultrasonic shock disk, it can effectively control the size of the nanoparticles, increase the efficiency of the particles themselves, reduce the non-specific toxicity, and achieve the purpose of gene delivery. Through simple surface modification (Figure 8, circle IX) 'Can also be used to deliver _ sexually delivered β in the delivery of raw materials, can be analyzed by frequency doubling technology. Or in the calibration of protein, long _ observation of egg from (four) molecular action and movement. After cell calibration can be Perform high-resolution biopsies analysis, and because of the frequency-doubled technique, it will not cause damage. 'This technology is difficult to analyze stem cell differentiation. 1342787 Table 1: Lipid nanoparticles with different formula synthesis Diameter (nm) '· * DOTAP PEG-DSPE Contains no iron oxide (Fe3〇4) Encapsulated oxidized male (Fe3〇4) 75 25 28.5 ± 1.6 30.2 ± 0.8 50 50 27.0 ± 1.1 26.1 ± 4.6 25 75 24.9 ± 0.9 32.4 ± 0.6 10 90 23.6 ± 1.8 37.7 ± 5.9 • 0 100 18.9 ± 5.7 30.7 ± 5.6 DOTAP. 1,2-I-(oleryloxy)-3-(trimethyl hydroxy)propanol (1 2-bis(di〇|eoyloxy) -3-(tri-methylarnonio) propane) PEG-DSPE: Polyethanol-bisstearate PEG2000-1,2-distearoyl-sn-glycero-3^phosphoethanolamine
