Actually, when observe it, tested it using the material which is similar that I adorned it to DNA to confirm it how much the density of fluorescence molecules can measure if there is it. The fluorescence molecules which it modified to DNA is FITC and TAMURA、Fluorescein in substitution for FITC, used Rhodamin B in substitution for TAMURA in artificial experiment.<br clear="all"></td></table>

N-cetyltrimethylammonium bromide (CTAB, 1.0009 g) was first dissolved in 50 ml of pure water by heating. After cooling to room temperature, aqueous ammonia (13 ml) and ethanol (75 ml) were added. The mixture was stirred for 15 min and TEOS (1.94 ml) added rapidly while stirring was continued. TEOS (30 μl) and APTES (30 μl) were introduced later. The mixture was allowed to stir for 2 h to give rise to white precipitates. The solid product was filtered, washed with deionized water and methanol, and dried in air. meso porous silica is synthesized Particle and pour site was determined by SEM observation.To remove the surfactant template (CTAB), the white powder was refluxed for 16 h in a solution of 1.00 ml of HCl (37%) and 80.00 ml of methanol followed by extensively washing with deionized water and methanol. Afterwards when we absorb it and filter it. After absorbing it, having filtered it, we remove water by putting meso porous silica in the vacuum state. The resulting surfactant-removed amine-functionalized MSN (MSN-NH2) was placed under high vacuum to remove the remaining solvent in the mesopores. The MSN-NH2 (50 mg) was reacted with succinic anhydride (1.00 g) in N,N-dimetylformamide solution (20 ml) under N2 gas for 8 h with continuous stirring.After a thorough water wash, the carboxylated nanoparticles (MSN-COOH) were activated using EDC (0.1471g) and sulfo-NHS (0.132g) in a MES buffer (pH 6.0) for 15 min at room temperature with continuous stirring. Twenty microliters of PBS buffer (100mM, pH7.4) was then added in the mixture, followed by the addition of TAMRA labeled DNA (5μl 100μM) at room temperature with continuous stirring for 6 h and washing in PBS buffer (0.1 M,pH 7.4) to form the resultant DNA-conjugated nanoparticles (MSN-DNA or -cDNA).
