Researchers develop magneto-nano sensor chip to detect cancer

Searching for biomarkers that can warn of diseases such as cancer while they are still in their earliest stage is likely to become far easier thanks to an innovative biosensor chip developed by Stanford University researchers.

Rapid detection and profiling of cancer cells in fine-needle aspirates

Using a new type of paramagnetic nanoparticle and a nuclear magnetic resonance (NMR) system built into a microfluidic device, a team of investigators at the Massachusetts General Hospital and Harvard Medical School has created an assay system capable of detecting as few as two cancer cells in 1 microliter of biological fluid. In addition, the new assay requires little sample processing and produces results in less than 15 minutes.

Implantable device offers continuous cancer monitoring

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.

New device could track tumor's growth

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but only offer a snapshot of the tumor at a single moment in time.

Hybrid nanoparticles image and treat tumors

By combining a magnetic nanoparticle, a fluorescent quantum dot, and an anticancer drug within a lipid-based nanoparticle, a multi-institutional research team headed by members of the National Cancer Institute's (NCI) Alliance for Nanotechnology in Cancer has created a single agent that can image and treat tumors. In addition, this new nanoparticle is able to avoid detection by the immune system, enabling the particle to remain in the body for extended periods of time.

Scientists develop nanometer-sized 'cargo ships' to target and destroy tumors

Scientists have developed nanometer-sized 'cargo ships' that can sail throughout the body via the bloodstream without immediate detection from the body's immune radar system and ferry their cargo of anti-cancer drugs and markers into tumors that might otherwise go untreated or undetected.

Dual-mode nanoparticles image tumors using MRI and PET

Medical imaging represents one of the most used and useful procedures in the oncologist's diagnostic toolkit, even though each of the most useful techniques-magnetic resonance imaging (MRI), computerized tomography x-ray imaging (CT), and positron emission tomography (PET) scanning-has its own set of limitations.

Better magnetic nanoparticles

Using a polymer coating designed to resemble the outer surface of a cell membrane, a team of investigators led by Steve Armes, Ph.D., of the University of Sheffield in the United Kingdom, has created a highly stable, biocompatible magnetic nanoparticle expected to improve the sensitivity of magnetic resonance imaging (MRI).

Low-field magnetic separation of monodisperse Fe3O4 nanocrystals

Whether the goal is to separate different types of cells or molecules, methods that rely on the age-old principle of magnetism are a staple among researchers.

Scientists develop magnetic nanoparticles for medicine

Magnetic iron oxide nanoparticles have already proven their utility for imaging metastatic breast cancer lesions in sentinel lymph nodes, and numerous groups are attempting to use iron nanoparticles in other imaging applications.
