- FIG. 1 General detection method (A) of DNA hybridization on DNA chip and sandwich hybridization process (B) using probe nanoparticl DNA with light scattering of hybridized probe nanoparticle DNA as detection method in the invention. And figure 1 (B) shows detection method based on light scattering to detect hybridization between target DNA and capture DNA on DNA chip. That is, the detection method of DNA hybridization of the invention is actually similar with general detection method based on complementary DNA hybridization to hybridize target DNA with capture DNA, target DNA with nanoparticle-DNA probe. Detection method of general DNA hybridization process is as following.
- Capture DNA which hybridize with complementary target DNA is immobilized on surface of silicon wafer, glass slide or plastic slide (capture DNA used in the invention is also called probe DNA in some papers, while in the invention we call it capture DNA which immobilized on chip surface and hybridize with target DNA), target DNA with specific sequence hybridize with capture DNA and the rest region of target DNA hybridize with probe nanoparticle DNA. Not hybridized target DNA in sample and buffer solution are removed, we can know what kind of target DNA are present in sample through detection of signaling probes. Although not shown in figure, sometimes for PCR amplification reaction, fluorescent dye molecules have been introduced from the beginning of the reaction to conjugate fluorescent dye molecule with target DNA.
- our detection method of DNA hybridization is based on detection of light scattering and nanoparticles are used as signaling probes with no need of fluorescent dye molecules for signaling. Rather than, it is important to control nanoparticle size and concentration to get certain degree of light scattering, and the conjugation methodCfigure 1 (B)) of nanoparticle-DNA is important.
- Light scattering phenomenon used in detection of DNA hybridization is dependent on nanoparticle size and in proportion to six square of nanoparticle radius, the volume and mass of nanoparticle increase 1,000 times when the radius of nanoparticle increases 10 times, while light scattering of nanoparticle increase one million times.
- Detection of DNA hybridization on DNA chip based on light scattering in our invention is as following.
- Sample is injected into chamber of DNA chip which contain capture DNA.
- Target DNA hybridize with complementary capture DNA and not hybridized part of target DNA are left.
- probe DNA conjugate with nanoparticle and we call it probe nanoparticle DNA.
- DNA probe conjugated with nanoparticle hybridize with the remaining region of target DNA, such hybridization is called sandwich hybridization.
- Nanoparticle is not just the meaning of particle with nanometer size. Particles of several micrometer can be seen by naked eye or by digital camera, smaller particles can also be observed by low cost laser scanner (flat bed scanner) based on light scattering. That is, even if the nanopart icles are small enough we can also detect light scattering phenomenon of nanopart icles using low cost instrument.
- Figure 2 show scheme of the other kind of nanoparticle used in our invention-dye-doped silica nanoparticle synthesis in water-in-oil microemulsion. And TEM image of such nanoparticles with diameter of 50 nm.
- Figure 3 is the scheme of conjugation of DNA probe with silica nanoparticle to form probe nanoparticle DNA used in our invention of detection method of DNA hybridization. The synthesis of probe nanoparticle DNA will be described more detail in following part.
- silica nanoparticles are used and amine groups are introduced to the surface of silica nanoparticles.
- amine groups are introduced to the surface of silica nanoparticles through silanization of 3- aminopropyltrimethoxysilane.
- Silanization is widely used method of introducing amine, sulfide, hydrocarbon groups to the surface of silica nanoparticles. The process is as follow, in reaction on glass slide surface, the R is substituted with OH group.
- the silanized amine group can link to specific protein through interaction with aldehyde group.
- aldehyde group For example, through glutaraldehyde, avidin can be attached to the surface of silica nanoparticles. Such avidin attached silica nanoparticle can react with 3'-biotinalated DNA through specific avidin-biotin interaction to conjugate nanoparticle with DNA probe, thus probe nanoparticle DNA as mentioned above can be synthesized.
- Avidin as well as streptavidin are widely used for their strong interaction with biotin.
- Avidin has four reaction region due to its tetramer structure.
- biotin is one kind of vitamin H small molecule and is widely used to link to one end of DNA. The whole process is to react avidin attached nanoparticle with 3'-biotinalated DNA and wash repeatedly to give probe nanoparticle DNA.
- silica particles with different size can be ordered easily, amine-modified or carboxy-modified silica nanoparticles can also be synthesized or ordered easily.
- FIG. 4 shows the silanization of nanoaparticle and immobilization process of capture DNA.
- the above method is to introduce thiol group and immobilize oligonucleotide on glass slide to obtain capture DNA which hybridize with target DNA. It is possible to introduce amine, carboxy, sulfide and hydrocarbon group to the surface of nanoparticle through silanization to conjugate with DNA.
- nanoparticle is conjugated with target DNA.
- DNA chip on which capture DNA is immobilized, the nanoparticle-target DNA hybridize with capture DNA.
- hybridization between target DNA and capture DNA can be detected.
- Target DNA-nanoparticle can be synthesized as mentioned before, for example, through interaction between avidin and biotin after introduction of biotin to target DNA and introduction of avidin to nanoparticle.
- FIG 1 (B) various method can be used dependent on individual obviously. Such example clearly show that using target DNA-nanoparticle can also detect hybridization between target DNA and capture DNA based on detection of light scattering of nanoparticles.
