Fig. 3: Demonstration of different modes of iCarP illumination on rat hearts.
From: A biodegradable, flexible photonic patch for in vivo phototherapy
a, b ICarP supporting color change in illumination, the same device delivered light of (i) 405 nm, (ii) 520 nm, (iii) 660 nm. c, d Pulsatile illumination at 1 Hz, (i), (ii), (iii) shows the on-off-on switch. e, f ICarP illumination with increasing intensity over time. White arrows indicate the optical fibers.
