3D-Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Endovascular interventions—i.e., minimally invasive procedures that involve navigating guidewires and/or microcatheters through a patient’s vasculature to access target treatment sites—have emerged as a preferable alternative to traditional open surgery in many clinical contexts. Unfortunately, maneuverability constraints inherent to conventional guidewire-microcatheter systems can hinder effective navigation to target sites, elevating the risk of procedural complications or […]

Direct 3D printing of Vernier-enhanced Fabry-Pérot interferometers on fiber-tips for compact gas sensors

The detection of trace gases is crucial in environmental monitoring, industrial safety, and medical diagnostics. Optical sensing technologies, particularly those leveraging photothermal spectroscopy, offer high sensitivity and selectivity, enabling the identification of gases based on their unique absorption spectra. Among these, photothermal interferometry offers exceptional sensitivity due to its use of an interferometric signal transducer. […]
