Images from the top to the bottom for structure and TEM imaging with or without negative staining: there are a PNTs, b hemin-PNTs, and c hemin@PNTs. d CD spectra of PNTs, hemin-PNTs, and hemin@PNTs. e Zeta potential of PNTs, hemin-PNTs, and hemin@PNTs. f UV‒vis spectra of the PNTs, hemin-PNTs, and hemin@PNTs. UV‒vis spectra of g hemin-PNTs and h hemin@PNTs with various hemin:PNT molar ratios. i Standard curve of hemin. Data represent means ± SDs. (n = 3)
