Researchers at the University of Illinois have developed a novel method using ultrasound from a household humidifier to create complex nanocomposite materials. The technique produces porous nanospheres and encapsulated nanoparticles with potential applications in catalytic reactions, drug delivery, and molecular sieves.
Researchers have discovered the role of cadherin 23 protein in the mechanotransduction process that converts sound waves into electrical signals. The study provides insights into Usher syndrome and age-related hearing loss, suggesting a potential therapeutic target for treating deafness.
New nanotech imaging techniques offer improved precision in detecting tumors, including lymphatic drainage imaging for breast cancer, and molecular fingerprints for prostate and ovarian cancer. These advancements aim to improve diagnosis and treatment options for cancer patients.
Researchers have developed composite fibers containing varying percentages of carbon nanotubes, which can double stiffness, reduce shrinkage by 50%, and improve solvent resistance. Breaking up nanotube bundles could make these materials more accessible for commercial products.
A new study by Southern Methodist University researchers has found that nanoparticles, specifically buckyballs, can cause significant brain damage in fish within 48 hours. The study's lead author suggests further testing and assessment of the risks and benefits of these nanoparticles before their widespread use.
A new imaging probe detects small tumors in the brain, providing crucial information to surgeons during operations. The technology uses near-infrared fluorescence optical imaging to identify tumor margins and improve surgical treatment.
A recent study has revealed a connection between FAP, a protein involved in tadpole tail resorption, and accelerated tumor growth in humans. Researchers found that producing high levels of FAP in the tumor microenvironment promotes cancer growth. The study also explores the potential use of antibodies to block FAP's action.
Nanoparticles are designed to detect specific molecules and transport them using an electric field, allowing for accurate sensing. The device uses microscopic needles to take up tissue fluid and mix it with nanoparticles, which then move the samples to a detection area.
By blocking the activity of enzyme Icmt, researchers can prevent mutant Ras from developing and causing uncontrolled cell growth. This breakthrough may lead to new therapies for various types of cancer, including pancreatic, ovarian, colon, and lung cancers.
