According to a new study published in the journal PLOS Computational Biology, researchers can improve on conventional protein analysis methods by using tiny nanopores, which ‘scan’ the proteins as they pass through them.
Proteins perform vital functions of life. They digest food and fight infections and cancer. They are in effect nano-machines, each one of them designed to do a specific function. But how did they evolve to fulfil those needs, how did the genes encode the structure and purpose of proteins?
UC San Diego’s Chemists, Nanoengineers, and Materials Researchers might have just developed the ultimate natural sunscreen. They have created nanoparticles that imitate the behavior of natural melanosomes, melanin-generating cell structures that protect skin, eyes and other tissues from the destructive effects of UV radiation.
A team of researchers from Washington State University (WSU) have shown a method to supply a drug to a tumor by attaching it to a blood cell. The innovation would enable doctors to target tumors with anticancer drugs that might otherwise destroy healthy tissues.
A majority of cancer tumors contain regions of low oxygen concentration where cancer treatments based on the action of reactive oxygen species are unproductive. Recently, American researchers have created a hybrid nanomaterial that discharges a free-radical-generating prodrug within tumor cells upon thermal activation.
Nanodiamonds are synthetic industrial diamonds that measure only a few nanometers. Recently, nanodiamonds have attracted significant attention due to their ability to carry out targeted delivery of cancer drugs and vaccines, and for other applications. To date, there have been limited possibilities for imaging nanodiamonds.
Air is polluted by small particles associated with cardiovascular disease, which can result in premature death. However, it still remains a mystery as to how particles inhaled into the lungs can affect blood vessels and the heart.
A first-of-its-kind nanoparticle vaccine immunotherapy targeting several cancer varieties has been developed by researchers from UT Southwestern Medical Center.
In a new study, researchers show that engineered nanosponges that are encapsulated in the membranes of red blood cells can reduce the severity of infections caused by group A Streptococcus, the bacteria responsible for strep throat and life-threatening infections such as necrotizing fasciitis, or flesh-eating disease.
For many centuries, lens makers have worked hard to make a perfect lens with the ability to produce pristine and perfect images. In the year 1873, Ernst Abbe—a German physicist and optical scientist—found out the diffraction limit of the microscope.
