Magnetically separated multi-detecting SERS system for diagnosing overexpressed circulating miRNA of pancreatic cancer in serum |
초록 |
Pancreatic cancer is hard to cure, but can be treated when it is found early. So, early detection of pancreatic cancer is a significant key in cancer therapy. SERS is a promising tool for detecting single molecule in sample. We focused on rapid separating and detecting circulating miRNA of pancreatic cancer in blood serum. Here, magnetic nanocluster (MNC) capped with silica was functionalized with 2 nm gold nanoparticle (MNC@Si@Au) to increase its colloidal stability during miRNA conjugation and separation. Then, plasmonic-enhancing gold nanoparticle was employed to increase miRNA probe Raman signal. SERS signal of the system was successfully collected in blood-serum mimic system. |
