Abstract Fast frame rates are desirable in scanning transmission electron microscopy for a number of reasons: controlling beam dose, capturing situ events, or reducing the appearance scan distortions. While several strategies exist increasing rates, many impact image quality require investment advanced hardware. Here, we present an interlaced imaging approach to achieve minimal loss with faster...

In vitro and in vivo experiments were performed to evaluate the parameter of light dose rate as it relates to the efficiency of hematoporphyrin derivative (HPD)-induced photosensitization. Exponentially growing Chinese hamster ovary cells were incubated with HPD (25 micrograms/ml) and were then exposed to red light (630 nm) delivered at different dose rates. A total of five dose rates (0.5, 5.0...
