Fig. 1: COF characterization.
From: Crystallinity of covalent organic frameworks controls immune responses
a COF reaction scheme, condensation reaction between terephthalaldehyde and trifunctional tris(4-aminophenyl) benzene to form a 2D imine-linked COF. b PXRD spectra of different crystallinity of COFs. c DLS graphs of different crystallinity of COFs (d) FT-IR of COFs. e SEM images of TAPB-PDA COF particles with low (COF1), medium (COF3), and high (COF5) crystallinity, Scale bar = 1 µm, Representive SEM images of COF (n = 3). f A representative confocal image of DCs treated with COF1, green = cytosol, magenta = COF1, blue = nucleus, Scale bar = 25 µm. The arrow in the image indicates COFs, stained with RBITC, being phagocytosed by DCs.
