Integration of Magnetic Dispersive Solid-Phase Micro-extraction with HPLC for Precise Detection of Tumor Markers 1-Methyladenosine and 1-Methylinosine in Urine Samples from Breast Cancer Patients
To analyze 1-methyladenosine (m1A) and 1-methylinosine (m1I) in urine samples obtained from patients with breast cancer and healthy people, we used magnetic dispersive solid-phase micro-extraction (MDSPME) combined with high-performance liquid chromatography. The structure and morphology of magnetic nanoparticles, Fe3O4@GO, were investigated by FT-IR, XRD, TEM, and TGA. m1A and m1I in urine samples were enriched by the solid phase micro-extraction technology of Fe3O4@GO. Several parameters affecting the extraction efficiency, including adsorption time, pH, ionic strength, mass of adsorbent, extraction time, eluent solvent, elution time, and elution temperature, were researched and optimized. Under the optimized conditions, the corresponding linearity range of the two analytes showed a good linearity (r2 > 0.9998) and significant addition recoveries ranging from 88.50 to 109.38%, while the limit of detection was between 0.10 and 0.11 ng/mL. The enrichment factors of m1A and m1I were 108 and 134, respectively. The method was simple, sensitive, and reliable for the detection and purification with good detection limit, and it was suitable for the detection of m1A and m1I in urine samples. In addition, the analysis of modified nucleosides is of great value for the early diagnosis of patients with breast cancer.
期刊介绍:
Separation sciences, in all their various forms such as chromatography, field-flow fractionation, and electrophoresis, provide some of the most powerful techniques in analytical chemistry and are applied within a number of important application areas, including archaeology, biotechnology, clinical, environmental, food, medical, petroleum, pharmaceutical, polymer and biopolymer research. Beyond serving analytical purposes, separation techniques are also used for preparative and process-scale applications. The scope and power of separation sciences is significantly extended by combination with spectroscopic detection methods (e.g., laser-based approaches, nuclear-magnetic resonance, Raman, chemiluminescence) and particularly, mass spectrometry, to create hyphenated techniques. In addition to exciting new developments in chromatography, such as ultra high-pressure systems, multidimensional separations, and high-temperature approaches, there have also been great advances in hybrid methods combining chromatography and electro-based separations, especially on the micro- and nanoscale. Integrated biological procedures (e.g., enzymatic, immunological, receptor-based assays) can also be part of the overall analytical process.
