摘要
An integrated device for the detection of cancerous tissue including an optical fiber configured to receive at a first end modulated infrared light and to conduct the modulated infrared light from the first end to a second end; and a plasmonic metasurface, disposed on the second end of the optical fiber, configured to localize evanescent infrared light to sub-100 nanometer distances from the plasmonic metasurface of the optical fiber such that the localized evanescent infrared light penetrates only the membrane portion of a cell held against the second end, wherein the second end is configured to receive reflected light reflected from the membrane portion the cell, the reflected light including spectroscopic information indicative of whether the cell is noncancerous or cancerous.
