Due to the various clinical characteristics of the infections, it is difficult for physicians to give a precise diagnose in the first place. Annually, there were about 25.5 million cases of antibiotic administration in domestic hospitals and primary clinics. Antibiotics misuse and abuse will further increase the incidence of multiple-drug resistant bacteria. Though the introduction of the MALDI-TOF MS machine has improved the efficiency in pathogen detection. However, the machine is large, and the price of equipment and cost of each diagnostic is high. Besides, MALDI-TOF MS is still not capable of assessing the antibiotic susceptibility of the pathogenic bacteria. Therefore, an affordable and portable diagnostic platform with the capability to distinguish the diverse clinical pathogens remain highly needed. Raman spectrometer is an emerging technology for the detection of pathogenic bacteria. The detection process does not require the labeling of the sample. It is a non-invasive, non-destructive optical test, and water will not interfere with its signal. However, there is no stable and effective Raman-based pathogen diagnostic platform available so far. Thus, we aimed to build a cross-disciplinary team and to combine our expertise in clinical pathogen identification, design and manufacture of advanced Raman optical instrument, SERS reagent development, intelligent data analysis, and software development to establish the database of Raman spectra of several clinical pathogenic bacteria and to conduct preliminary research on big data integration and analysis. We expect that this project will establish a new Raman-based pathogen identification platform to improve the quality and efficiency of clinical pathogen diagnostic.質譜儀表面增強拉曼散射抗生素抗藥性MALDI-TOF MSSurface-enhanced Raman scatteringAntibiotic resistanceThe Construction and Application of the High-Sensitive Raman Spectral Database for Rapid Identification of Clinical Important Pathogens( I )=高靈敏度拉曼快篩技術於臨床重要致病菌檢測之數據庫建置與應用(1/3)
