Optical imaging in the second near‐infrared (NIR‐II, 900–1700 nm) window has been extensively investigated for bioimaging. However, a strong autofluorescence background from real‐time excitation light significantly reduces the images’ quality of NIR‐II fluorescence (FL) imaging. To resolve this issue, a NIR‐II self‐luminous small molecule (CLPD) based on bioluminescence (BL) resonance energy transfer...
Stimulus‐responsive fluorescence imaging modality shows great promise for detection of tumor due to the advantages of high sensitivity, simplicity and noninvasiveness. However, some non‐cancer regions including nodules and inflammation may also exhibit a stimulus‐related characteristic, which cause the problem of nonspecific responsiveness and then cause “false positive” results for tumor recognition...
2D molybdenum disulfide (MoS2) gives a new inspiration for the field of nanoelectronics, photovoltaics, and sensorics. However, the most common processing technology, e.g., liquid‐phase based scalable exfoliation used for device fabrication, leads to the number of shortcomings that impede their large area production and integration. Major challenges are associated with the small size and low concentration...
Micro‐supercapacitors (MSCs) based on mesoporous polyaniline patterned graphene are demonstrated. The synergic effect from both electron‐double‐layer‐capacitive graphene and pseudocapacitive mesoporous‐polyaniline leads to outstanding MSC device performances, in regard to excellent volumetric capacitance and rate capabilities, which further result in a high power density of 600 W cm−3, suggesting...
