Realizing the point-of-care tumor markers biodetection with good convenience and high sensitivity possesses great significance for prompting cancer monitoring and screening in biomedical study field. Herein, the quantum dots luminescence and microfluidic biochip with machine vision algorithm-based intelligent biosensing platform have been designed and manufactured for point-of-care tumor markers diagnostics. The employed quantum dots with excellent photoluminescent performance are modified with specific antibody as the optical labeling agents for the designed sandwich structure immunoassay. The corresponding biosensing investigations of the designed biodetection platform illustrate several advantages involving high sensitivity (~ 0.021 ng mL^-1), outstanding accessibility, and great integrability. Moreover, related test results of human-sourced artificial saliva samples demonstrate better detection capabilities compared with commercially utilized rapid test strips. Combining these infusive abilities, our elaborate biosensing platform is expected to exhibit potential applications for the future point-of-care tumor markers diagnostic area.

SAN ANTONIO — June 10, 2025 — Southwest Research Institute’s Dr. Craig DeForest discussed the latest accomplishments of NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission during a media event at the 246th American Astronomical Society meeting in Anchorage, Alaska. As the spacecraft constellation completes commissioning, early PUNCH data showed coronal mass ejections, or CMEs, as they erupted from the Sun and traveled across the inner solar system.

The innovation turns conventional RFID technology into a reliable sensing platform without requring wires, batteries or calibration.

Rice University student engineers have earned top international honors for a novel device that could redefine how humans interact with virtual environments. Their project, a wearable haptic wristband, claimed first place in the IEEE Circuits and Systems Society (CASS) Student Design Competition held in London May 27.
