Plasmonics enhanced nonlinear biological imaging.

(A) SHG imaging of neuroblastoma cells (A1) without nanoparticle (A2) enhanced SHG signal after addition of gold nanoparticle. Reprinted with permission from ref [27]. (B1) Silver nanoparticle enhanced THG imaging of wild type MBT2 cells treated with anti-Her2 antibody conjugated Ag nanoparticles. Reprinted with permission from ref [73]. (B2) Plasmon enhanced THG image of a NIH3T3 cell nucleus labelled with 10 nm gold nanoparticles followed by silver enhancement. Reprinted with permission from ref [26]. (C) THG images of a muscle tissue slice (C1) without and (C2) with silver nanoparticle enhanced detection. Gray and white circles indicates the region of THG enhancement from collagen fibers and muscle I-band respectively. Reprinted with permission from ref [74]. (D1) Gold nanoparticle surface plasmon enhanced autofluorescence image (red-yellow) of live Chinese Hamster Ovary cells, superimposed on the transmission image (blue) of the cell. Reprinted with permission from ref [26]. (D2) Surface plasmon-enhanced two-photon total-internal-reflection fluorescence microscopy image of cultured monkey kidney fibroblast cell membrane. Reprinted with permission from ref [77]. (E1) Transmission electron microscope (TEM) observation of macrophages with 50 nm gold nanoparticles, the images in the right display nanoparticles in the vacuole. Reprinted with permission from ref [92]. (E2) SERS images of macrophage cells cultured with 50 nm gold nanoparticles. The white arrows shows regions of high SERS signals. Reprinted with permission from Ref. [93]. (F1) Metal tip excited near field two-photon fluorescence image of photosynthetic membrane fragments of algae (Chlamydomonas reinhardtii). Reprinted with permission from ref [102]. (F2) Tip-enhanced CARS image of DNA network. Reprinted with permission from ref [103].
