@article{2682, abstract = {The living cell imaging using a two-photon microscope using gold nanoplates and nanoparticle aggregates was demonstrated. The dimensions of the nanoplates were determined through scanning electron microscopy (SEM) and atomic force microscopy. The height of a 100 nm base-length nanotriangle was around 10 nm, while the height of 300 nm base-length nanotriangle was around 12 nm. A spectrophotometer was also used to determine the extinction spectra of gold nanoparticle colloids. Two-photon-induced photoluminescence (TPIPL) under far-field excitation was tested for gold nanoplates on a glass substrate using two-photon laser scanning microscopy (TPLSM). It was observed that living-cell microscopic imaging can be carried out with TPIPL from gold nanoplates and aggregated nanosphere. This method provided a platform for developing tools for biological and biomedical studies.}, author = {Jiang, Yuqiang and Horimoto, Noriko N and Imura, Kohei and Matsui, Ko and Ryuichi Shigemoto}, journal = {Advanced Materials}, number = {22}, pages = {2309 -- 2313}, publisher = {Wiley-Blackwell}, title = {{Bioimaging with two-photon-induced luminescence from triangular nanoplates and nanoparticle aggregates of gold}}, doi = {10.1002/adma.200802312}, volume = {21}, year = {2009}, }
