Recurrent brain tumors are extremely difficult to treat because they often return after surgery, radiation, and chemotherapy, leaving patients with few options and limited time. Many tumors grow in locations that cannot be safely reached through open surgery, and repeat […]
Opioid overdoses often become fatal because they occur without a bystander present to administer naloxone, the medication that rapidly reverses opioid effects. Synthetic opioids such as fentanyl act quickly and powerfully, leaving individuals unconscious before they can seek help. Researchers
Many chronic conditions require frequent monitoring of biomarkers that cannot be measured easily with conventional wearables. Sweat‑based sensors often struggle with low fluid volume, while blood‑based tests require needles and clinical visits. Researchers at the Hong Kong Polytechnic University developed
Many neurological disorders are treated with electrical stimulation delivered through surgically implanted electrodes. These devices can help manage severe epilepsy, Parkinson’s disease, essential tremor, and other conditions when medications fail, but they require invasive brain surgery and place rigid metal
Magnetic Microparticles Provide a Less Invasive Method for Neural Stimulation Read More »
Glioblastoma remains one of the most difficult cancers to treat because its cells infiltrate healthy brain tissue, making complete surgical removal nearly impossible. Even when surgeons remove all visible tumor tissue, microscopic clusters often remain and lead to recurrence. The
Many medical devices that rely on light, such as pulse oximeters and wearable health sensors, struggle to perform consistently across different skin tones. Darker skin contains more melanin, which absorbs and scatters light, making it harder for optical devices to

Ovarian cancer is difficult to treat because it often spreads throughout the peritoneal cavity, making it challenging to deliver therapy precisely where it is needed. Standard approaches rely on surgery and systemic treatments that struggle to reach microscopic disease and
Implant Delivers Targeted Ovarian Cancer Therapy Directly Inside the Peritoneal Cavity Read More »
Gum disease often progresses because harmful bacteria disrupt the balance of the oral microbiome, leading to inflammation, bone loss, and long‑term damage to teeth. Conventional treatments such as antibiotics and antimicrobial photodynamic therapy remove both harmful and beneficial bacteria, which

Many wearable health sensors struggle to maintain reliable contact with the skin, especially when sweat, hair, bending, or stretching interfere with the electrode interface. These interruptions can distort biological signals and reduce the accuracy of devices used for monitoring chronic

People living with Parkinson’s disease often face the challenge of maintaining consistent medication levels throughout the day. The effectiveness of treatment depends on how well the body absorbs and metabolizes each dose, yet traditional monitoring methods require blood samples or
