A Au nano popcorn modified SWNCTs nano-hybrid for specific diagnosis of SK-BR-3 cancer cells. The left part shows the schematic illustration in the synthesis procedure its application in cancer cell diagnosis; middle part shows the Raman spectra of SWCNTs, Au nano popcorn modified SWCNTs nano-hybrid, and Au nano popcorn modified SWCNTs nanocomposites decorated with SK-BR-3 cancer cell and the right part the SERS intensity changes at 1590 cm⁻¹ after the addition of different amounts of SK-BR-3, MDA-MB human breast cancerous, and HaCaT normal skin cells to the aptamer modified nano-hybrid. B Schematic illustration of the synthesis of SWNCT-Ag-PEG-FA or SWNCT-Au-PEG-FA nano-hybrids for specific Raman imaging of KB cells and Raman images of SWNCT-Au-PEG-FA incubated with KB cells (middle part) and Hela cell (right part).
