Incorporation of AuNRs in the PLGA shell. (A) TEM images of two different length AuNRs (diameter ~25 nm) with absorption peaks centered at 650 and 785 nm. (B) Bright-field (left) and dark-field (right) optical micrographs of dispensed PLGA shell arrays functionalized with different length nanorods. In the bright-field image, the blue and red colors correspond to the 650 and 780 nm absorption nanorods. The colors are switched in the dark-field image because this shows the scattered component of light as compared to the transmitted in bright-field mode. (C) Vis–NIR spectra of PLGA shells loaded with different length nanorods.
