Fig. 3From: Innovations in biomedical nanoengineering: nanowell array biosensora Top and b 60°-tilted SEM images of large-area integrated Au nanobox arrays with a 400 nm inner square. The bilayer polymer was imprinted by UV-NIL with a 400 nm square pattern and subjected to 5 min of Au deposition, 5 min of ion milling, and 10 min of piranha cleaning. The scale bar of the insets is 500 nm [48]Back to article page
