Optical Biopsy to Spot Tumors Among Healthy Tissue

Researchers at Orel State University in Russia have developed a biopsy system that can distinguish between healthy and cancerous tissue in many clinical cases. The device is designed to address the difficulties that clinicians may experience when trying to obtain a biopsy of a liver tumor, where it can be difficult to know if the […]

Hairy Nanocrystals Capture Chemo Drugs

Researchers at Penn State working with collaborators have developed a nanomaterial that can ‘mop up’ chemotherapeutics in the bloodstream, helping to reduce off-target effects. The technology is intended for use in situations where a chemotherapeutic can be delivered precisely to the site of a tumor, and not in situations where it is de (Read more...)

New Hydrogel Material for Vocal Cord Repair

Researchers at McGill University developed a tough hydrogel that can resist mechanical forces found in the body. However, the material still provides a friendly environment for encapsulated cells to grow and enables the deep perfusion of blood and other tissue fluids. The injectable biomaterial may be useful in repairing tissues that experience con (Read more...)

Fish-Shaped Microrobots to Deliver Chemotherapy to Tumors

Researchers from the University of Science and Technology of China, working with outside collaborators, have developed shape-shifting microrobots that are designed to be guided to a target area in the body using magnets, and then release a drug cargo in response to the local environment. The application that the researchers have pursued involves gu (Read more...)

Cold Cap Therapy for Chemo Patients: Interview with Kate Dilligan, CEO of Cooler Heads Care

Cooler Heads Care, a medtech company based in San Diego, created Amma, a cold cap therapy device that aims to help chemotherapy patients to preserve their hair. Hair loss is a very common side-effect of chemo, and poses a significant psychological challenge for patients who are already struggling with their diagnosis and treatment. Simply cooling [ (Read more...)

Weighing Cancer Cells for Chemotherapy Susceptibility Testing

A collaboration between groups at MIT and Dana-Farber Cancer Institute led to the creation of a system that allows for quick determination of the susceptibility of cancer cells to specific drugs, without the need to rely on genomic markers. The technique consists of flowing the cells through vibrating microchannels, which lets the researchers obtai (Read more...)

Handheld Photoacoustic Device for Lymph Node Assessment

Researchers at Pohang University of Science & Technology in South Korea have developed a handheld photoacoustic device that can locate sentinel lymph nodes near the armpit. The technology could help clinicians to locate the correct lymph node from which to take a biopsy when checking for breast cancer metastases. At present, this process involv (Read more...)

Pancreatic Organoids Grown Inside Synthetic Gel

A team at MIT has developed a technique to grow organoids, both from healthy and cancerous pancreatic tissue, using a synthetic gel that predictably mimics the pancreatic extracellular environment. Compared with naturally derived materials, the synthetic gel is consistent from batch to batch, meaning that it leads to more reproducible and predictab (Read more...)

Oscillating Magnetic Field Shrinks Glioblastoma Tumor

At the Houston Methodist Neurological Institute, researchers have developed a device that generates a magnetic field and used it to successfully shrink a glioblastoma tumor in a patient volunteer. The device is worn on the head each day during treatment, and uses an oscillating magnetic field to disrupt biochemical processes in cancer cells. While (Read more...)

Nanoparticles for Tumor Imaging and Cancer Urine Testing

Scientists at MIT have announced that they developed novel nanoparticles to detect cancer in urine samples. As well as detecting the presence of tumors, the nanoparticles can also accumulate at tumor sites and function as an imaging agent, helping to identify their location. These multifunctional particles could be very useful for routine cancer sc (Read more...)

AI System Spots Prostate Cancer During Routine CT Scans

Researchers at RMIT University in Melbourne, Australia, created an AI system that can identify prostate cancer during routine CT scans. It is typically difficult to spot prostate cancer in CT images, and the radiation makes CT unsuitable as a screening modality. However, if men are undergoing abdominal or pelvic scans for other reasons, this latest (Read more...)

Inexpensive Filter Isolates Circulating Tumor Cells

Researchers at Kumamoto University in Japan have designed an inexpensive and convenient filter that can isolate circulating tumor cells from as little as 1 mL of patient blood. The highly sensitive filter can successfully work in samples containing as few as five tumor cells in 1 mL of blood, and does not require expensive equipment […]

Trojan Horse Virus Makes Tumors Destroy Themselves

Researchers at the University of Zurich have developed a virus-based therapy that causes a tumor to destroy itself. They modified an adenovirus, which is a common virus that typically infects the respiratory tract and which is already widely used in medicine, to deliver genetic material that codes for an anti-cancer protein. In a sneaky move, [&hel (Read more...)

Mantis Shrimp-Inspired Camera to Detect Tumors During Surgery

Researchers at the University of Illinois Urbana-Champaign have developed a hexachromatic camera that can assist with tumor imaging during surgical removal. The device is inspired by the mantis shrimp which can perceive twelve colors, compared with just three colors that can be perceived by the human eye. The new camera can visualize tumors in the (Read more...)

Ultrasonic Biopsy Needle for Larger Tissue Samples

Researchers at Aalto University in Finland have developed an ultrasonically actuated needle that can retrieve a large amount of tissue during a biopsy, without the pain and complications associated with using bigger needles. The technique could be very useful when clinicians need to obtain tissue samples for molecular tumor diagnostics, since obtai (Read more...)
