Abstract Blind nasojejunal tube (NJT) insertion with radiographic confirmation often results in initial malposition and repeated imaging in neonates, raising concerns about procedural delays and cumulative radiation. Point-of-care ultrasound (POCUS) enables real-time, radiation-free guidance, but multicenter neonatal evidence has been limited. We conducted a multicenter, real-world retrospective cohort study across three tertiary NICUs in China (May 2023–May 2025).

Abstract Acoustic wave sensors with a high sensitivity and small size are highly desired for a wide variety of important and emerging applications such as photoacoustic gas sensing and bio-imaging. Here we present an ultracompact optical fiber acoustic sensor based on an optomechanical resonator that is directly in situ printed on the end face of a standard single-mode optical fiber by using an optical 3D μ-printing technology.

Ultrasensitive optofluidic enzyme-linked immunosorbent assay by on-chip integrated polymer whispering-gallery-mode microlaser sensors Optical whispering-gallery-mode (WGM) microcavities offer great promise in ultrasensitive biosensors because of their unique ability to enable resonant recirculation of light to achieve strong light-matter interactions in microscale volumes.
