A) Schematic representation shows SERS based cancer cell detection using aptamers attached GNPOPs modified SWCNT. B) TEM image shows aggregation of aptamer conjugated GNPOPs functionalized SWCNTs on cancer cell surface. C) Absorption profile showing variation of absorption spectra of bio-conjugated SWCNT hybrid GNPOPs due to the addition of SK-BR-3 cancerous cells. In this case, we have used 10 µg/ml modified SWCNT and 1.5 nM GNPOP hybrid.
