Nir fluorescence imaging. Simultaneous NIR‐II fluorescence and white‐light (WL) imaging of VEGF is validated in an orthotopic rat colorectal cancer model. This NIR‐II endoscopy system is a generalizable design, and it is compatible with the most of current clinic endoscopies. Semiconducting polymer nanoparticles (SPNs) emitting in the second near-infrared window (NIR-II, 1000–1700 nm) are promising materials for deep-tissue optical imaging in mammals, but the brightness is far from satisfactory. Herein, we developed a molecular design strategy to boost the brightness of NIR-II SPNs: structure planarization and twisting. By integration of the strong absorption. An activatable nanoprobe for imaging breast cancer metastases through near infrared‐I (NIR‐I)/NIR‐II fluorescence imaging and multispectral optoacoustic tomography (MSOT) imaging was designed. With a dihydroxanthene moiety serving as the electron donor, quinolinium as the electron acceptor and nitrobenzyloxydiphenylamino as the. The NIR-II fluorescence imaging was performed with a NIR-II Imaging System, which was manufactured by Suzhou NIR-Optics Co., Ltd. The laser used for excitation is an 808 nm laser with an intensity of 80 mW cm −2. The signals at 1060 nm and 1340 nm were collected by using 930 nm long-pass (LP) & 1150 nm short-pass (SP) filters, and 1250 nm LP.

Fluorescence imaging in the second near-infrared window (NIR-II) holds promise for real-time deep tissue imaging. In this work, we investigated the NIR-II fluorescence properties of a liposomal formulation of indocyanine green (ICG), a FDA-approved dye that was recently shown to exhibit NIR-II fluorescence. NIR-II bioimaging is able to explore deep-tissues information in the range of centimeter, and to obtain micron-level resolution at the millimeter depth, which surpass the performance of NIR-I fluorescence imaging. The key of fluorescence bioimaging is to achieve highly selective imaging thanks to the functional/targeting contrast agent (probe).

The incubation protocol was the same as that used in the cell uptake experiment. For imaging in the NIR-II window, a 1,000 LP filter was used for obtaining fluorescence imaging, and the suitable exposure time was 20 ms. Mice and samples were imaged at different time points (2, 6, 12, 24 h). MRI of Mice Finally, the AIE dots were applied in high performance NIR-II fluorescence imaging and NIR-I photoacoustic (PA) imaging: visualization of abdominal vessels, hind limb vasculature, and cerebral vessels with high signal to background ratios was performed via NIR-II imaging; Moreover, PA imaging has also been performed to clearly observe tumors in. The imaging technology has to replace the missing view of the open site. Alongside an optimal image, it is helpful to receive additional information that increases the precision of the surgical technique. This information is supplied, for instance, by NIR/ICG fluorescence imaging – an OPAL1® technology from KARL STORZ. Invisible UV ink is only visible under an ultraviolet light. Our UV LEDs light module, FluoroVu, features a narrow emission spectral band, is an effective tool and especially made for smartphones to easily verify and document the presence of UV fluorescence security features embedded in many products such as security barcodes for anti-counterfeiting, currency, travelers' checks, credit cards.

The development of multifunctional agents for simultaneous tumor targeting and near infrared (NIR) fluorescence imaging is expected to have significant impact on future personalized oncology owing to the very low tissue autofluorescence and high tissue penetration depth in the NIR spectrum window. C … In this work, a NIR photosensitizer (APN-CyI) which could be activated by APN not only for tumor imaging but also for photodynamic therapy was firstly developed.As depicted in Scheme 1, after being recognized, APN-CyI would be hydrolyzed, thereby forming CyI-OH, which was a hemicyanine fluorophore with NIR feature, good light stability, solubility and low biological toxicity [], especially. The imaging technology has to replace the missing view of the open site. Alongside an optimal image, it is helpful to receive additional information that increases the precision of the surgical technique. This information is supplied, for instance, by NIR/ICG fluorescence imaging – an OPAL1® technology from KARL STORZ. Fluorescence imaging in the second near-infrared (NIR-II) regime with less light scattering is a more promising method for detecting cortical vessels than traditional visible and NIR-I modes. Methods: Clinically approved dye indocyanine green (ICG) was used for NIR-II fluorescence imaging. Here, for the first time, we developed two NIR-II.
