Interlocking Metals and Polymers for Magnetically Controllable Therapeutic Microrobots
Researchers at ETH Zurich have developed a technique to create tiny microrobots with interlocking polymer and metal parts that can be controlled using magnetic fields. The magnetic metal components can move within the polymer frame, providing locomotion, and the tiny bots are small enough to traverse blood vessels, potentially functioning as vehicl (Read more...)
How To Make Almost Anything – Exclusive Interview with Dr. Neil Gershenfeld, MIT Center for Bits and Atoms
Dassault Systèmes’ annual Science in The Age of Experience Conference has become one of my favorite conferences. It is a platform for thoughtful and innovative discussion centered around how science affects so many aspects of our lives, as well as an intermingling of distinguished scientists, engineers, and other professionals from all (Read more...)
Hydrogel Contact Lens Measures Biomarkers in Tears
Researchers at the Terasaki Institute in Los Angeles have developed a prototype of a contact lens that can assist with tear sampling for diagnostic purposes, and to also improve tear flow to potentially prevent dry eye disease. The hydrogel lens contains microchannels through which tears can travel and testing chambers where electrochemical and col (Read more...)
Highly Realistic 3D Printed Human Hearts
Physical models of organs and tissues have many uses in clinical medicine, particularly when preparing for challenging surgeries. Naturally, the heart is commonly modeled using 3D printing to most closely mimic the nuances of unique patient anatomies. This is useful when preparing for procedures such as mitral valve repairs, but typically this is a (Read more...)
OtoSet Automatic Ear Cleaning Device FDA Cleared
SafKan Health, a firm based in Tucson, Arizona, won FDA clearance and is about to release its OtoSet automated ear cleaning system. Designed to address impacted earwax, which affects millions of people and often causes hearing loss, the OtoSet is a pair of headphones with irrigation and suction tips on the inside. These spray water […]
Symani Microsurgical System Cleared in Europe
Medical Microinstruments (MMI), a company based outside of Pisa, Italy, won the European CE Mark of approval for its Symani robotic surgical system. The product provides 7-20X scaling of hand movements, automatically removing tremors to allow for safe microsurgical and supermicrosurgical procedures. It is hoped that this impressive new device can h (Read more...)
Red Blood Cells Deliver Nanoparticles to Provoke Immune Response to Lung Metastases
Researchers at Harvard’s Wyss Institute have developed a way to deliver immune-stimulating agents to lung metastases. Their system involves nanoparticles loaded with an immune-stimulating agent that are attached to red blood cells. When injected into the blood stream, the red blood cells shed the nanoparticles as they squeeze through the narr (Read more...)
Implantable Bladder Wrap for Improved Urinary Control
Researchers at Penn State have developed an implantable device that coils around the bladder to detect when the bladder is full and assist with emptying it by contracting on-demand. The device is intended to treat underactive bladder, a condition in which incomplete bladder emptying leads to irregular and uncomfortable urination. “Researchers (Read more...)
Stretchable Fiber-Optic Sensors for Skin-Like Sensation
Researchers at Cornell University have developed stretchable sensors that can detect sensations such as strain, pressure, and bending, much like human skin. Deformation is measured through changes in optical paths within the flexible fiber optic sensors. By providing a sense of ‘touch’, the sensors could provide additional functionality (Read more...)
FDA Clears Most Powerful Clinical MRI
GE Healthcare won FDA clearance for its SIGNA 7.0T MRI scanner, currently the most powerful device available for clinical applications. A high end scanner’s magnetic field typically tops out at 3 Tesla, but the new device goes all the way up to 7 Tesla to provide an unprecedented look at highly detailed anatomy. Certainly intended […]
Rapid Identification of Antibiotic-Resistant Infections: Interview with Jong Lee, CEO at Day Zero Diagnostics
Antibiotic resistance is a growing concern, with some predictions suggesting that routine surgery could be unacceptably risky in a future where many antibiotics have become obsolete. Part of the problem lies in the time it takes clinicians to diagnose an antibiotic-resistant infection. Current techniques involve lab technicians culturing a bacteria (Read more...)
Elastomeric Respirator Mask Senses Fit and Filter Saturation
Researchers at Brigham and Women’s Hospital and Massachusetts Institute of Technology have designed a new respirator, conceived as an improvement on standard N95 masks. The transparent respirator contains sensors that allow users to know if the mask is fitting snugly and alerts them when the filters need to be replaced. The mask, called the t (Read more...)
Implantable Biodegradable Sensor Measures Gases Inside The Body
Researchers at Penn State have developed an implantable sensor that can measure levels of NO and NO2 gases in the body, both of which are medically relevant. Consisting of silicon and magnesium, the sensor is flexible and completely biodegradable, and so does not need to be removed after implantation. Measuring levels of NO and NO2 […]
Inhalable Nanobody Therapy Deactivates SARS-CoV-2
Researchers at the University of Pittsburgh have developed a new antibody-type therapy for SARS-CoV-2, the causative virus for COVID-19. The treatment exploits “nanobodies” – tiny antibody fragments – that are harvested from llama blood. The new nanobody therapy can be used in an inhalable form that may deactivate the virus (Read more...)
Earwax Sampling Device for Easy Cortisol Measurement
Researchers at University College London and King’s College London have developed a device that allows for easy earwax sampling, with the goal that the wax could be a convenient and reliable way to measure cortisol levels. The device can be used by a patient at home to obtain a sample of earwax and is less […]
Flexible Patch Monitors and Treats the Beating Heart
Researchers at the University of Houston and colleagues have developed a flexible epicardial patch which can monitor heart function and even administer treatments, such as thermal ablation and heart pacing. The device can harvest power directly from the movement of the beating heart and its flexibility means that it conforms well with the epicardia (Read more...)
Microneedle Bandage Detects Malaria in Minutes
Researchers at Rice University have developed a microneedle patch that can rapidly detect the presence of malaria in interstitial fluid.
