Impedance Cytometry for Rapid Antibiotic Susceptibility Testing
Scientists at Nara Institute of Science and Technology in Japan have come up with a method to rapidly determine the antibiotic susceptibility of a bacterial sample, such as a patient sample from a non-healing infected wound. The technique is based on impedance cytometry, which involves a high-throughput single cell analysis of the bacterial cells. (Read more...)
Neck Sensor Helps Masked Clinicians Communicate
Researchers at Pohang University of Science & Technology in South Korea developed an auditory sensor that lets people wearing face masks, such as clinicians, to communicate more easily. The device is essentially a wearable microphone that picks up the vibrations of the skin in the neck that occur when someone talks. The researchers hope that [& (Read more...)
Algae-Based Microrobots Deliver Antibiotics within Lungs
Researchers at the University of California San Diego have developed a microrobot system to treat bacterial pneumonia. The microrobots consist of living algal cells that can swim very effectively in biological fluids, allowing them to navigate throughout the lungs and deliver drugs to difficult-to-reach areas. The algal cells are studded with antib (Read more...)
Perfusion Machine Restores Donor Liver for Transplant
Clinical researchers at the University of Zurich in Switzerland have created a perfusion machine to store donor livers before transplant. We originally reported on the machine back in 2020, but now the team has announced that they stored and treated a damaged liver in the machine, which would ordinarily not be suitable for transplantation. After [& (Read more...)
Wearable Sweat Sensor Warns of Impending Cytokine Storm
Researchers at the University of Texas at Dallas, in collaboration with a company called EnLiSense, developed a wearable electrochemical sweat sensor that can detect chemokines in sweat, alerting the wearer and clinicians to a viral or bacterial infection. The device also warns of an impending cytokine storm, where high levels of inflammatory molec (Read more...)
Magnetic Tentacle Robot Travels Deep into Lungs
Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope is used to investigate the lungs, but this cannot pass into very […]
Finger Clip for Blood Pressure Monitoring
At the University of Missouri a team of researchers developed a custom finger clip device that can continuously measure a variety of vitals, including blood pressure. The novel device represents a new way to measure vitals, and contains two commercial photoplethysmography (PPG) sensors that operate at two different points on the finger. This approa (Read more...)
3D-Printed Origami Tube for Low-Cost Ventilators
Researchers at Simon Fraser University in Canada have developed a low-cost portable ventilator that uses a 3D-printed origami tube rather than a conventional airbag. The volume of the tube can be modified by changing the angles in the origami folding plates. As up to 95% of the components of the ventilator are 3D printable, the […]
EXALT Model B Single-Use Bronchoscope: Interview with Dave Pierce, Boston Scientific
Boston Scientific recently announced FDA clearance of the EXALT Model B single-use bronchoscope, intended for bedside procedures in intensive care units or in the operating room. As a single-use device that boasts high quality imaging and suction capabilities, the bronchoscope is ready to go out of the packaging, which means it mitigates the risk o (Read more...)
Biomaterial-Based Vaccine Against Bacterial Infection
Researchers at the Harvard Wyss Institute have developed a biomaterial-based vaccine technology that could provide prophylactic protection against bacterial infection and septic shock. The technology is delivered as a biomaterial scaffold. Once inside the body, it captures bacterial pathogens and then recruits and activates dendritic cells to initi (Read more...)
GARNET Pathogen Filter to Treat Sepsis: Exclusive with Nisha Varma, COO of BOA Biomedical
Sepsis is caused by an uncontrolled spread of infectious pathogens and release of toxins that can lead to systemic inflammation, multi-organ failure, and even death. The pathogens responsible for causing sepsis are usually difficult to identify, and patients are routinely treated with broad spectrum antibiotics. However, dead pathogens remaining in (Read more...)
Wireless Sensor Measures Deep Tissue Oxygen Levels
Researchers at the University of California, Berkeley have developed an ultrasound-powered implantable sensor that can measure oxygen levels in tissues deep within the body and transmit these data to an external device. The technology could be useful in monitoring transplant viability or oxygen exposure in preterm infants. It also has potential to (Read more...)
Sweat Sensor Warns of Impending COVID-19 Cytokine Storm
Researchers at the University of Texas and EnLiSense, a Texas startup, have developed a skin sweat sensor that can measure cytokine levels continuously for up to 168 hours. The technology has been adapted so that it can detect cytokines involved in the deadly cytokine storms that occur in patients with COVID-19 and other illnesses, such […]
Robots Measure Vitals to Minimize Interactions with COVID Patients
Researchers at Simon Fraser University in Canada have developed three different robots that can sense and measure patients’ healthcare parameters, including electrocardiograms, oxygen levels, respiration rates, and temperature. One of the robots, comprising a robotic arm, contains electrodes in its fingertips, and can take measurements when i (Read more...)
Microfluidics and AI Microscopy for Hemoglobin Measurements
Researchers at the Indian Institute of Science and SigTuple Technologies, a company based in Bengaluru, India, have developed a method to inexpensively measure hemoglobin levels in small-volume blood samples.
