[0180] In addition, as shown in Table 20 above, as a result of additionally producing the peptides represented by M and then measuring the hydrophobicity and retention time (RT) for the sequence of each of the peptides, it was possible to produce various sequences showing a retention time (RT) of 30 seconds to 20 minutes. In order to quantify the same biomarker in multiple samples using the peptide, a binding moiety that recognizes the analyte, such as a detection moiety composed of a different sequence for each sample, may be provided, so that multiple samples may be pooled into one and quantified simultaneously.

[Preparation Example 6] (2) Production of Peptides Represented by M and Measurement of Retention Time

[0181] In order to confirm the simultaneous detection ability of the detection sensor of the present disclosure as described in Preparation Example 5 above, the peptide (TLVPR) represented by SEQ ID NO: 688 and the peptide (SLVPR) represented by SEQ ID NO: 669 were synthesized, and then the retention time (RT) for each of the sequences of these peptides was measured. The results of the measurement are shown in Table 21 below. In addition, these compounds were prepared at a concentration of 1.5 μg/ml, and then the peak intensity of each peptide fragment was determined through the mass-to-charge ratio of each peptide fragment in a mass spectrometer, and the results are shown in FIGS. 10a and 11a; and the magnified peaks are shown in FIGS. 10b and 11b.

[Preparation Example 7] (1) Synthesis of Units and M

[0182] FIG. 12 shows the kinds of exemplary amino acids or amino acid analogs that may correspond to X.sub.1 to X.sub.m in Formula 2 of the present disclosure. In addition, FIG. 13 shows examples of M that may be obtained by polymerizing these amino acids or amino acid analogs.

[Preparation Example 8] (2) Synthesis of Units and M

[0183] As shown in FIG. 14, a disaccharide that may be M of the present disclosure was prepared. The disaccharide M was degraded by lactase or under an acidic condition into two monosaccharides that are isomers of each other, and thus the sensitivity in mass spectrometry thereof was doubled.

[Experimental Example 1] Experiment for Simultaneous Detection of Four Peptides Represented by M

[0184] In order to confirm the ability to simultaneously detect the peptides represented by M according to the present disclosure, the peptides having the sequences shown in Table 22 below were detected by mass spectrometry MRM, and the results are shown in FIG. 15.

[0185] As shown in FIG. 15, it was confirmed that it was possible to simultaneously detect the peptides having the four sequences shown in Table 22 above.

[Experimental Example 2] (1) Examination of Sensitivity to Peptides Represented by M

[0186] In order to confirm the amplification effect resulting from the repetition of the peptide sequence of the present disclosure, each of the peptide (LTLK) of SEQ ID NO: 652 in Table 20 above and the polymer (LTLKLTLK) composed of two repeats of the peptide was trypsinized, and then the intensity of the peak thereof was measured using a mass spectrometer. The results of the measurement are shown in FIGS. 16 and 17. The mass spectrometer sensitivity (CPS) as a function of the polymerization number was calculated and the results are shown in FIG. 18.

[0187] As shown in FIGS. 16 and 17, compared to the intensity of the peak of the peptide (LTLK) of SEQ ID NO: 652, the intensity of the peak of the polymer (LTLKLTLK) composed of two repeats of the peptide was doubled. In addition, as shown in FIG. 18, it could be confirmed that when the peptide was repeated twice, the sensitivity was exactly doubled, suggesting that when the peptide is polymerized, the sensitivity increases as much as the polymerization number.

[Experimental Example 3] (2) Examination of Sensitivity to Peptides Represented by M

[0188] In order to confirm the amplification effect resulting from the repetition of the peptide sequence of the present disclosure, the peptide fragment (FLK) of SEQ ID NO: 690 or a peptide composed of 2, 4 or 6 repeats of this fragment was produced. Then, each of these compounds was prepared at a concentration of 1 pM, and trypsin was added in an amount of 1:20 to 100 (w/w) with respect to the compound, followed by cleavage into FLK fragments at 37° C. The peptide fragments were dried completely and resuspended, and the mass-to-charge ratio of the FLK peptide fragment was input using a mass spectrometer (MRM mode). The area of the chromatogram was calculated, and the change in the peak intensity as a function of the polymerization number of the peptide fragment was measured, and the results of the measurement are shown in FIG. 19.

[0189] As shown in FIG. 19, it could be confirmed that, when the peptide fragment represented by FLK of SEQ ID NO: 690 is polymerized to form a polymer composed of repeats of the peptide fragment, the detection sensitivity increases in proportion to the polymerization number.

[Experimental Example 4] (1) Evaluation of Diagnostic Ability of Detection Sensor

[0190] In order to evaluate the diagnostic ability of the detection sensor of the present disclosure, a protein detection test was performed as shown in FIG. 20. First, a target protein for cancer diagnosis was selected, and then an aptamer specific to the target protein was prepared, and an aptamer-MNP conjugate was produced in the same manner as in Preparation Example 4. Thereafter, each well was treated with the produced aptamer-MNP conjugate, and each well was treated and reacted with the blood isolated from a person in need of diagnosis. After the reaction was completed, each well was treated with a magnetic field, and a photograph of the blood after treatment is shown in FIG. 21.

[0191] As shown in FIG. 21, impurities other than the target protein that specifically binds to each aptamer could be removed from each well. Thereafter, reaction with each of proteins 1 to 4 through CuCl.sub.2 treatment, removal of the remaining CuCl.sub.2, treatment of each well with the complex compound represented by Chemical Formula 10, and removal of the remaining complex compound were sequentially performed, so that only the [M].sub.n-L.sub.1-N.sub.1-analyte-second binding moiety-carrier conjugate shown in FIG. 22 remained in each well. Then, each well was trypsinized, followed by filtration to obtain peptides.

[Experimental Example 5] (2) Evaluation of Diagnostic Ability of Detection Sensor—Simultaneous Measurement of Multiple Samples

[0192] In order to confirm the diagnostic ability of the detection sensor of the present disclosure, simultaneous quantification of multiple samples was performed in the same manner as in Experimental Example 5, and the results are shown in FIG. 23.

[0193] Protein (albumin) present in human samples was selected. Accordingly, an aptamer specific to the protein was prepared, and an aptamer-MNP conjugate was produced in the same manner as in Preparation Example 4. Next, as in Experimental Example 5, each of wells 1 to 4 was treated with the produced aptamer-MNP conjugate, and then each well was treated and reacted with the blood isolated from a person in need of diagnosis. After the reaction was completed, each well was treated with a magnetic field as shown in FIG. 21. As a result, impurities other than the protein that bind specifically to the aptamer could be removed from each well. Thereafter, reaction with each of proteins 1 to 4 through CuCl.sub.2 treatment, removal of the remaining CuCl.sub.2, treatment of each well with the complex compound represented by Chemical Formula 10, and removal of the remaining complex compound were sequentially performed, so that only the [M].sub.n-L.sub.1-N.sub.1-analyte-second binding moiety-carrier conjugate shown in FIG. 23 remained in each well. M having different sequences were applied to the samples, respectively. Then, each well was trypsinized, followed by filtration to obtain peptides. As a result of analyzing the obtained peptides by a mass spectrometer, the polymer of the detection sensor treated into well 1 was composed of a peptide having a retention time (RT) of 14 minutes, the polymer of the detection sensor treated into well 2 was composed of a peptide having a retention time (RT) of 17.5 minutes, the polymer of the detection sensor treated into well 3 was composed of a peptide having a retention time (RT) of 21.5 minutes, and the polymer of the detection sensor treated into well 4 was composed of a peptide having a retention time (RT) of 24.5 minutes. It could be seen that, for samples 1, 2 and 4, the expression levels of the proteins exceeded the normal reference value, but for sample 3, the expression level of the protein was normal, suggesting that the detection sensor has excellent ability to simultaneously detect an analyte in biological samples with high sensitivity even in simultaneous measurement of multiple samples.

[Experimental Example 6] (2) Evaluation of Diagnostic Ability of Detection Sensor

[0194] In order to evaluate the diagnostic ability of the detection sensor of the present disclosure, albumin was prepared as an analyte and then prepared at concentrations of 0, 0.33 μg/μl, 0.65 μg/μl and 1.3 μg/μl. Thereafter, for the detection of albumin, a complex compound consisting of an albumin-specific peptide (CB3GA)-rhodamine-(SLVPR (SEQ ID NO: 689)).sub.5 having the structure shown in FIG. 24 was produced. Thereafter, the complex compound was allowed to react with albumin in a ratio of 3 to 6 equivalents, and then an unreacted portion of the compound was removed. Thereafter, as shown in FIG. 25, the (SLVPR).sub.5 peptide compound was cleaved into SLVPR fragments by treatment with trypsin, and the change in sensitivity as a function of the concentration of the analyte was measured using a mass spectrometer, and the results are shown in FIG. 27. Meanwhile, for comparison of the diagnostic ability of the detection sensor of the present disclosure, the fluorescence intensity of rhodamine was measured as shown in FIG. 26 before trypsin treatment, and the results are shown in FIG. 28.

[0195] As shown in FIGS. 27 and 28, it could be confirmed that, when the peptide polymer ((SLVPR).sub.5) composed of 5 repeats of the SLVPR peptide fragment was used for albumin detection, the amplification effect could be produced as the peptide polymer was cleaved into 5 SLVPR peptide fragments due to trypsin treatment, and in particular, the sensitivity increased more than 6.5 times compared to that in the fluorescence measurement method.

[0196] As described above, it was confirmed through the Examples of the present disclosure that the detection sensor of the present disclosure could detect the analyte with high sensitivity through amplification, and simultaneous detection was also possible through the production of peptides having various sequences.
