The quartz crystal microbalance technique with dissipation monitoring and the complementary optical microscopy technique were used for monitoring cell adhesion on an RGD-functionalized supported lipid bilayer. A critical interligand RGD spacing of nearly 80 nm was estimated for cell adhesion when an RGD spacing of 10 nm was necessary to observe flattened cells on a fluid surface.
Three into one will go: The consecutive combination of three orthogonalchemoselective reactions (oxime ligation, thioether addition, and copper(I)‐catalyzed alkyne–azide cycloaddition (CuAAC)) in a sequential one‐pot approach allows the syntheses of highly sophisticated biomolecular compounds without intervening isolations and protection schemes (see picture; ODN=oligodeoxynucleotide).
