Point-of-care News
Paper-Based Test Scans for Multiple Biomarkers in Human Serum
LOS ANGELES, May 11, 2023 — Researchers led by UCLA professor Aydogan Ozcan developed a deep learning-enabled biosensor for multiplexed, point-of-care (POC) testing of disease biomarkers. POC biosensors provide remote and resource-limited communities with an economical,...
Saliva Test Instantly Detects Coronavirus with Lasers
BRUSSELS, April 14, 2020 — Responding to the European Commission’s call to tackle the coronavirus pandemic, photonics scientists are developing a new, rapid, noninvasive “optical biosensor” demonstrator that will detect COVID-19 in humans as soon as it is...
Lensless On-Chip Microscopy Platform Shows Slides in Full View
STORRS, Conn., Feb. 20, 2020 — Guoan Zheng, a University of Connecticut (UConn) professor of biomedical engineering, has published his findings on a successful demonstration of a lensless on-chip microscopy platform in Lab on a Chip. Zheng suggests his platform eliminates several...
Portable Biosensor Uses Light at Nanoscale to Detect Sepsis in Minutes
LAUSANNE, Switzerland, Jan. 28, 2020 — Time is critical when diagnosing sepsis, but the tests currently used to identify this disease can take up to 72 hours. Researchers at the Laboratory of Bionanophotonic Systems (BIOS) at École Polytechnique Fédérale de Lausanne...
Quantum Dots Deliver Vaccines, Encode Vaccination History in the Skin
CAMBRIDGE, Mass., Jan. 7, 2020 — Using fluorescent quantum dots, an MIT research team has created a way to administer vaccinations and record a patient’s vaccination history in the skin. The researchers developed a microneedle platform that can selectively deliver...
System Uses Artificial Intelligence for Placental Analysis
UNIVERSITY PARK, Pa., Dec. 4, 2019 — Placentas can provide critical information about the health of the mother and baby; yet, in the U.S., only about 20% of placentas are assessed by pathology exams after delivery. A new approach from researchers at The Pennsylvania State University...
Microfluidic Device with Fluorescent Sensor Detects Ebola
ROCHESTER, N.Y., May 15, 2019 — A faculty-researcher at Rochester Institute of Technology (RIT) has developed a prototype microdevice with biosensors that can detect the Ebola virus. The microfluidic device is an automated chip with a highly sensitive fluorescence sensing unit...
Point-of-Care Device Could Improve Thyroid Cancer Screening
BARCELONA, Spain, March 21, 2018 — A team of international researchers developed a point-of-care device that could enable consistent and cost-effective screening for thyroid nodules. This novel device builds on the current ultrasound standard with a hybrid optics/ultrasound probe....
Handheld Spectrometer Wirelessly Transmits Data to Smartphone
HAIKOU, BEIJING and HANGZHOU, China, Nov. 17, 2017 — A wireless handheld spectrometer that is smartphone-compatible could make it easier and more economical to acquire spectral images of everyday objects and in the future could be used for point-of-care medical diagnosis in remote locations. The...
Multichannel Optical Biosensor May Detect Cancer
PULLMAN, Wash., Oct. 20, 2016 — An eight channel smartphone spectrometer has been developed which can detect human interleukin-6 (IL-6), a known biomarker for lung, prostate, liver, breast and epithelial cancers.
The Connected World: Banking on Innovations in Photonic Sensors
Apr 28, 2016 — The Internet of Things (IoT) is about to change how we live in almost every conceivable way, from driverless cars and smart cities to precision agriculture. In fact, the economic impact per year of all things IoT is projected to be $11.1 trillion a...
Simpler, more cost-effective biosensing
GÖTEBORG, Sweden – There are two challenges facing optical label-free biosensing, especially for clinical applications, according to Alexandre Dmitriev of Chalmers University of Technology.< “The system should be able to work in physiological fluids –...
