📣Call for Reading: #Article Handheld Biosensor System Based on a Gradient Grating Period Guided-Mode Resonance Device By Chien Chieh Chiang, Wen-Chun Tseng, Wen-Tsung Tsai, Cheng-Sheng (Jason) Huang, National Yang Ming Chiao Tung University https://lnkd.in/g_iu8rPA Abstract: Handheld biosensors have attracted substantial attention for numerous applications, including disease diagnosis, drug dosage monitoring, and environmental sensing. This study presents a novel handheld biosensor based on a gradient grating period guided-mode resonance (GGP-GMR) sensor. Unlike conventional GMR sensors, the proposed sensor’s grating period varies along the device length; hence, the resonant wavelength varies linearly along the device length. If a GGP-GMR sensor is illuminated with a narrow band of light at normal incidence, the light resonates and reflects at a specific period but transmits at other periods; this can be observed as a dark band by using a complementary metal oxide semiconductor (CMOS) underneath the sensor. The concentration of a target analyte can be determined by monitoring the shift of this dark band. We designed and fabricated a handheld device incorporating a light-emitting diode (LED) light source, the necessary optics, an optofluidic chip with an embedded GGP-GMR sensor, and a CMOS. LEDs with different beam angles and bandpass filters with different full width at half maximum values were investigated to optimize the dark band quality and improve the accuracy of the subsequent image analysis. Substrate materials with different refractive indices and waveguide thicknesses were also investigated to maximize the GGP-GMR sensor’s figure of merit. Experiments were performed to validate the proposed handheld biosensor, which achieved a limit of detection (LOD) of 1.09 × 10−3 RIU for bulk solution measurement. The sensor’s performance in the multiplexed detection of albumin and creatinine solutions at concentrations of 0–500 μg/mL and 0–10 mg/mL, respectively, was investigated; the corresponding LODs were 0.66 and 0.61 μg/mL. #optical #biosensor #resonance #open_access

A project led by M. Hassan Arbab, associate professor in the Department of Biomedical Engineering, aims to differentiate healthy vs. diseased skin using terahertz imaging to help burn victims. Terahertz imaging is a way of “seeing inside” materials, like skin, using a special type of invisible light. The light is non-ionizing, meaning it is safer than X-rays, and able to penetrate materials like skin, clothing or paper.

Happy to share our latest work on flexible mesoporous gold electrodes for minimally invasive biomedical applications. By integrating these electrodes into a soft robotic catheter, we demonstrated a flexible and electrically stable platform for field potential recording, bioimpedance sensing, and cardiac pacing, paving the way for next-generation minimally invasive medical devices. This work was carried out by Michael Abraham Listyawan and led by my good friend and long-term collaborator, A/professor Hoang-Phuong Phan. Congratulations to the entire team on this outstanding achievement! https://lnkd.in/gxTrfSHB #MesoporousGold #BiomedicalEngineering #Bioelectronics #SoftRobotics #MedicalDevices
