A Team of Russian Physicists from ITMO University have discovered that spherical silicon nanoparticles can be effectively heated up, and concurrently produce light based on their temperature. According to the researchers, these properties united with a good biocompatibility will facilitate usage of the semiconductor nanoparticles in nanosurgery and photothermal therapy.
Scientists from the Massachusetts General Hospital (MGH) have discovered an astonishing new role for the immune cells known as macrophages—enhancing the efficaciousness of nanoparticle-delivered cancer treatments.
Some of the favorable attributes of nanomedical systems are autonomous targeting and delivery of drugs at their location of action. At present, a group of Dutch Researchers have developed a nanomotor that includes an antitumor drug enclosed within a self-assembled, self-propelled stomatocytes, carried over the cellular membrane and delivered into the cell on receiving a chemical redox signal for disassembling the vesicle membrane.
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.
