Ultrafast Intelligent Sensor for Integrated Biological Fluorescence Imaging and Recognition.

Fluorescence imaging and recognition are core technologies in targeted medicine, pathological surgery, and biomedicine. However, current imaging and recognition systems are separate, requiring repeated data transfers for imaging and recognition that lead to delays and inefficiency, hindering the capture of rapidly changing physiological processes and biological phenomena. To address these problems, we propose an integrated intelligent sensor for biological fluorescence imaging and ultrafast recognition.

Narrowband absorption far-red organic photodetector for photoplethysmography.

Narrowband absorption organic semiconductors are highly attractive for spectrally selective photodetection applications requiring lightweight and customizable devices. Although narrowband absorption photodetectors have achieved success in the visible range, far-red (650-750 nm) devices are scarce. The far-red wavelength range is relevant for applications in medical diagnostics, such as photoplethysmography for blood oxygen saturation detection.
