This invited Team Profile was created by the Zheng Lab (UHN, Toronto, Canada), the CEPOF BioPhotonics Lab (USP, São Carlos, Brazil), and the BiOPI Lab (UC Chile, Santiago, Chile). They recently published an article on an Indocyanine Green (ICG) nanoemulsion in which 100 % dimerization and J‐aggregation occurs spontaneously afford a nanostructured shell of dimeric ICG (Nano‐dICG). This material demonstrates superior photothermal conversion efficiency, photostability, and structure stability over ICG, giving an ultra‐stable phototheranostic platform for photoacoustic imaging and effective photothermal therapy.

The subduction zone off the west coast of South America marks the convergence of the oceanic Nazca plate and the continental South America plate. Nazca-South America convergence over the past 23 million years has created the 6-km-deep Peru-Chile trench, 150?km offshore. High pressure between the plates creates a locked zone, leading to deformation of the overriding plate. The surface area of this locked zone is thought to control the magnitude of co-seismic release and is limited by pressure, temperature, sediment type and fluid content. Here we present seafloor deformation data from the submerged South America plate obtained from a combination of Global Positioning System (GPS) receivers and acoustic transponders. We estimate that the measured horizontal surface motion perpendicular to the trench is consistent with a model having no slip along the thrust fault between 2 and 40?km depth. A tsunami in 1996, 200?km north of our site, was interpreted as being the result of an anomalously shallow interplate earthquake. Seismic coupling at shallow depths, such as we observe, may explain why co-seismic events in the Peruvian subduction zone create large tsunamis. [ABSTRACT FROM AUTHOR]
