Discoidal Polymeric Nanoconstructs
(A) Schematic representation of the process for the synthesis of DPNs. (B) Scanning electron microscopy images of the silicon master templates for circular, elliptical, and square DPNs (left column); optical images of PVA sacrificial templates for circular, elliptical, and square DPNs (central column), filled with a fluorescent polymeric paste; TEM images of circular, elliptical and square DPNs (right column). Red fluorescent is obtained by dispersing lipid-Rhodamine B complexes within the nanoconstruct polymeric matrix.53 DPN, discoidal polymeric nanoconstruct; PDMS, polydimethylsiloxane; PVA, poly(vinyl alcohol); TEM, transmission electron microscopy.
