Summary Electrochemical sensors convert chemical signals from target analytes into electrical signals for detection, making them valuable for biomedical applications. Sensitivity is crucial as clinical biomarkers are often present at very low levels, and electrochemical sensors help monitor drug concentrations like doxorubicin in biofluids. A team led by Professor Hyongsok Tom Soh at Stanford developed […]

Summary Researchers from Stanford University have developed an implantable, ultrasound-powered drug delivery device that integrates nanoparticles and electronics for targeted, on-demand drug release. The device uses a potentiostat to control drug release by measuring the current between electrodes, and it operates wirelessly through ultrasound, making it ideal for deep tissue implantation. The system allows precise […]

Summary Before smartphones, memorizing phone numbers was a common necessity, often accomplished by mentally repeating the number. The brain similarly solves short-term memory problems by maintaining patterns of neuronal activity. Researchers, led by Professors Shaul Druckmann and Nuo Li, studied how this occurs in mice by engaging their short-term memory. They discovered that two brain […]

Summary Hair cortisol concentration (HCC) offers a promising non-invasive method to track stress hormone levels over time, particularly during pregnancy. Cortisol, crucial in the body’s stress response, is deposited into hair, reflecting past hormone levels. A study led by Dr. Lucy King at Stanford University examined HCC dynamics in pregnant women and postpartum, finding significant […]

Summary Researchers at Stanford University, led by Dr. Leanne Williams, are developing a framework that links brain circuit activity, observed via fMRI scans, to specific depression and anxiety symptoms. Traditional psychiatric labels fail to reflect the biological underpinnings of mental health conditions, but the study focuses on neural circuit dysfunctions, such as the default mode […]

Summary Researchers are exploring the use of soft, flexible, wireless bioelectronics to detect neuromotor disorders in infants, addressing the challenges of current bulky and wired systems. Traditional assessments, like Prechtel’s tool, predict cerebral palsy in infants by analyzing general movements (GMs), but these methods rely heavily on video monitoring and expert evaluation. A new approach, […]

Summary Researchers at Stanford University have developed an innovative biosensor using the giant magnetoresistive (GMR) effect to enable early, sensitive, and automated detection of hepatocellular carcinoma (HCC), the most common type of liver cancer. The biosensor leverages a magnetic-based immunoassay to detect biomarkers like alpha-fetoprotein (AFP) and C-reactive protein (CRP) in real time. It offers […]

Summary Researchers at Stanford University and POSTECH have developed a smart contact lens that monitors blood sugar levels through a chemical reaction involving glucose in tears. The lens uses a combination of gold and platinum nanoparticles embedded in a polymer hydrogel to catalyze this reaction, producing electricity proportional to glucose levels. This technology offers continuous, […]

Summary A Stanford University research team, led by Professor Zhenan Bao, has developed a novel strategy for creating flexible, stretchable, and durable skin-inspired electronics using a molecular design approach. The team introduced the covalently-embedded in-situ rubber matrix (iRUM) strategy, which enables high-performance field-effect transistors (FETs) with stretchable polymer semiconductors and dielectrics. This innovation ensures that […]
