We describe the experimental method to deposit nanostructured oxide thin films by nanosecond Pulsed Laser Deposition (PLD) in the presence of a background gas. By using this method Al-doped ZnO (AZO) films, from compact to hierarchically structured as nano-tree forests, can be deposited.

This method describes high yield in vitro synthesis of both capped and uncapped mRNA from a linearized plasmid containing the Gaussia luciferase (GLuc) gene. The RNA is purified and a fraction of the uncapped RNA is enzymatically capped using the Vaccinia virus capping enzyme. In the final step, the mRNA is transfected into HeLa cells and cell culture supernatants are assayed for luciferase activity.

Non-fouling PEG silane monolayer was desorbed from individually addressable ITO electrodes on glass by application of a reductive potential. Electrochemical stripping of PEG-silane layer from ITO microelectrodes allowed for cell adhesion to take place in a spatially defined fashion, with cellular patterns corresponding closely to electrode patterns.
FAQs
The cap creates a fixed space between the endoscope lens and tissue, reducing abrupt changes in viewing distance as the instrument contacts the mucosa. That spacing helps keep the visual field open and makes the image more stable during examination or treatment. A steadier view can support more controlled inspection and intervention.
As the endoscope advances, the cap can gently flatten or lift mucosal folds that obstruct the lens or limit access. This action may expose areas that are difficult to inspect directly and provide a more consistent orientation within the lumen. The resulting control is especially relevant when anatomy makes forward advancement or lesion approach challenging.
Because the attachment is clear, it can maintain the spacing and tissue-contact benefits of a cap without blocking the endoscopist’s view through the distal tip. This allows the clinician to use the cap while continuing visual examination. Preserving visibility supports lesion inspection and helps guide instruments during minimally invasive treatment.
In gastrointestinal endoscopy, the cap is placed over the distal tip before or during an examination or intervention, where it maintains a controlled relationship between the lens and mucosa. The endoscope can then be advanced while the cap helps preserve an open field and consistent orientation, supporting both diagnostic inspection and treatment.
Cap-assisted techniques can support several gastrointestinal procedures, including biopsy, polypectomy, and endoscopic mucosal resection. By helping maintain visualization and control near the target, the cap may make it easier to approach a lesion and perform the intended intervention with greater precision. Its role complements the endoscope rather than replacing the therapeutic technique.
A cap may be particularly useful when clinicians encounter difficult anatomy, limited visualization, or mucosal folds that interfere with inspection. By creating a more stable viewing distance and helping maintain orientation, it can improve procedural control in these settings. The overview also associates cap assistance with greater efficiency during examination and treatment.
