Detection of human cancerous cell lines. (A) Change in fluorescence intensities (F − F₀) for 4 different cancer cell lines HeLa (Cervical), MCF7 (Breast), HepG2 (Liver) and NT2 (Testes) using nanoparticle-polymer supramolecular complexes. Each value is average of 6 parallel measurements. (B) Canonical score plot for the two factors of simplified fluorescence response patterns obtained with NP–PPECO₂ assembly arrays against different mammalian cell types. The canonical scores were calculated by LDA for the identification of 4 cell lines.
