NIR-II emissive donor-acceptor-donor fluorophores for dual fluorescence bioimaging and photothermal therapy applications.

Fluorescence bioimaging with near-infrared II (NIR-II) emissive organic fluorophores has proven to be a viable noninvasive diagnostic technique. However, there is still the need for the development of fluorophores that possess increased stability as well as functionalities that impart stimuli responsiveness. Through strategic design, we can synthesize fluorophores that possess not only NIR-II optical profiles but also pH-sensitivity and the ability to generate heat upon irradiation.

Early exposure of rotating magnetic fields promotes central nervous regeneration in planarian Girardia sinensis.

Magnetic field exposure is an accepted safe and effective modality for nerve injury. However, it is clinically used only as a supplement or salvage therapy at the later stage of treatment. Here, we used a planarian Girardia sinensis decapitated model to investigate beneficial effects of early rotary non-uniform magnetic fields (RMFs) exposure on central nervous regeneration.

A comparison of laser ultrasound measurements and finite-element simulations for the dispersion behavior of antisymmetric flexural modes propagating along wedge tips with coatings.

Antisymmetric flexural (ASF) modes are antisymmetric types of guided waves propagating along the tip of wedge-shaped waveguides. Acoustic sensors frequently rely on the detection of small mass changes that result from binding a coated layer coupled to the active sensor surface. While a layer is coated on one of the wedge's surfaces, another type of sensor can be potentially developed based on detecting the change of ASF velocity.
