| 英文摘要 | Surface enhanced raman scattering (sers) is a trace detection technique that extends even to single molecule detection. its potential application to the noninvasive recognition of lung malignancies by detecting volatile organic compounds (vocs) that serve as biomarkers would be a breakthrough in early cancer diagnostics. this application, however, is currently limited by two main factors: (1) most voc biomarkers exhibit only weak raman scattering; and (2) the high mobility of gaseous molecules results in a low adsorptivity on solid substrates. to enhance the adsorption of gaseous molecules, a zif-8 layer is coated onto a self-assembly of gold superparticles (gsps) in order to slow the flow rate of gaseous biomarkers and depress the exponential decay of the electromagnetic field around the gsp surfaces. gaseous aldehydes that are released as a result of tumor-specific tissue composition and metabolism, thereby acting as indicators of lung cancer, are guided onto sers-active gsps substrates through a zif-8 channel. through a schiff base reaction with 4-aminothiophenol pregrafted onto gold gsps, gaseous aldehydes are captured with a 10 ppb limit of detection, demonstrating tremendous prospects for in vitro diagnoses of early stage lung cancer. |
