“…[27] A significant enhancement of fluorescence intensity, together with the high throughput and fine microfluidic control over reagents with lab-on-chip techniques, makes the nanowrinkles promising low-cost substrates for ultrasensitive and ultrafast detection for biomedical applications. [36] In addition, such nanoscale features, along with ease of surface functionalization, make the gold wrinkles a potentially useful substrate for studying cell membrane dynamics. [37] Experimental Fabrication of Nanowrinkles and Discrete Wrinkled Flowers: For biaxial wrinkles, gold of varying nanometer thicknesses was deposited on a Shrinky-Dink sheet (or KSF50-C; Grafix, 2 cm  1 cm) using sputtering (SEM coating system; Polaron).…”
