A dual-functional benzobisthiadiazole derivative as an effective theranostic agent for near-infrared photoacoustic imaging and photothermal therapy by Huang, Shuo, Upputuri, Paul Kumar, Liu, Hui, Pramanik, Manojit, Wang, Mingfeng

“…Herein, we report a theranostic agent based on a narrow-­‐bandgap small molecule, benzo[1,2-c;4,5-c’]bis[1,2,5]thiadiazole-4,7-bis(9,9-dioctyl-9H-­fluoren-­2-yl)thiophene (denoted as BBT-2FT), with strong absorption of near infrared (NIR) light. Colloidal nanoparticles composed of BBT­‐2FT show photoacoustic signal intensity 10 times higher than that of blood, and high photothermal conversion efficiency (η=40%) under irradiation of 800-nm laser light that kills over 90% HeLa cells in 10 mins.…”

Three-dimensional modeling of near-field beam profiles from grating couplers using a deep neural network by Lim, Yu Dian, Tan, Chuan Seng

“…As the formfactor of ion traps reduces, the ion-trapping height decreases, and may unavoidably fall into the reactive near-field region of SiPh gratings. In this study, a deep neural network (DNN) modeling technique is developed as a rapid alternative to generate reactive near-field beam profiles of light coupled from SiPh gratings, as compared to the conventional finite-difference time-domain (FDTD) technique. …”
