Historic properties face challenges preserving and maintaining their physical heritage, as well as digitally sharing and accessing their history in a virtual environment. They are now utilizing new advanced imaging methods to research their cultural heritage artifacts. Recent advanced imaging in historic Civil War-era houses demonstrated the integration of imaging techniques and data to support conservation of these structures and research into their history and contents. New technical systems, including the latest narrowband multispectral imaging systems and higher resolution cameras, raise major challenges in not only the integration of new technologies, but also the ability to store, manage and access large amounts of data. Integration, preservation, access and collaboration with the image data from this program requires implementation of standardized digitization and data archiving practices.

The II-VI semiconducting compounds are of particular interest due to the ability to compositionally tune them to detect infrared radiation in the 0.5 to 30 μm range. With the demand for advanced imaging systems, there is an immediate need for bulk II-VI materials with improved compositional homogeneity and structural perfection. The performance of optical semiconductors is very sensitive to the presence of defects such as dislocations, precipitates, and boundaries.

AbstractThree-dimensional visualization of cellular and subcellular-structures in histological-tissues is essential for understanding the complexities of biological-phenomena, especially with regards structural and spatial relationships and pathologlical-diagnosis. Recent advancements in tissue-clearing technology, such as Magnified Analysis of Proteome (MAP), have significantly improved our ability to study biological-structures in three-dimensional space; however, their wide applicability to a variety of tissues is limited by long incubation-times and a need for advanced imaging-systems that are not readily available in most-laboratories. Here, we present optimized MAP-based method for paper-thin samples, Paper-MAP, which allow for rapid clearing and subsequent imaging of three-dimensional sections derived from various tissues using conventional confocal-microscopy. Paper-MAP successfully clear tissues within 1-day, compared to the original-MAP, without significant differences in achieved optical-transparency. As a proof-of-concept, we investigated the vasculature and neuronal-networks of a variety of human and rodent tissues processed via Paper-MAP, in both healthy and diseased contexts, including Alzheimer’s disease and glioma.

Abstract In 2019, the French-German Research Institute of Saint-Louis (ISL) is celebrating its 60th anniversary. Since the beginning, advanced imaging technologies were one of the institute’s flagship areas of research and, from the Cranz-Schardin camera to computational optics, ISL never stopped innovating. Each technological innovation is a testimony to its time, and the research works in visionics make no exception to this rule. Each decade was marked by innovations that made it possible to develop means of vision or visualization, which ensure that our institute remains at the forefront of the research in this field. High-speed cameras, holography, lasers, or active imaging systems developed at ISL are examples of this. The science of photon, photonics, still has a bright future ahead, and there is no doubt that the latest discoveries and technological advances in this field will be applied to systems that will allow our armed forces to maintain their technological superiority and our soldiers to carry out their missions with greater security.

The study of different genes, chromosomes and the spatiotemporal relationship between them is of great significance in the field of biomedicine. CRISPR-Cas9 has become the most widely used gene editing tool due to its excellent targeting ability. In recent years, a series of advanced imaging technologies based on Cas9 have been reported, providing fast and convenient tools for studying the sites location of genome, RNA, and chromatin. At the same time, a variety of CRISPR-Cas9-based imaging systems have been developed, which are widely used in real-time multi-site imaging in vivo. In this review, we summarized the component and mechanism of CRISPR-Cas9 system, overviewed the NIR imaging and the application of NIR fluorophores in the delivery of CRISPR-Cas9, and highlighted advances of the CRISPR-Cas9-based imaging system. In addition, we also discussed the challenges and potential solutions of CRISPR-Cas9-based imaging methods, and looked forward to the development trend of the field.
