Hafnium nanoparticles that home onto microfractures in bone make the tiny cracks visible in spectral or color computed tomography (CT) imaging. Researchers at the University of Illinois at Urbana-Champaign and the University of Maryland created the nanotechnology to work in conjunction with spectral molecular imaging developed by New Zealand-based MARS Bioimaging Ltd. (MBI). The research appeared in Advanced Functional Materials.
A team led by researchers at Washington State University (WSU) has developed a nanoparticle technology to deliver cell-killing drugs to shut down the overactive immune response that can cause damage or death in diseases like stroke and sepsis without affecting other cell types or compromising the immune system.
There are a pair of approved CAR T drugs, Yescarta (axicabtagene ciloleucel) from Gilead Sciences Inc. and Kymriah (tisagenlecleucel) from Novartis AG, that have been available since 2017 for a few hematological cancers including some lymphomas and leukemias. But little is known about how these engineered chimeric antigen receptor T cells that both target CD19, an antigen prevalent in the cells of many B-cell malignancies, move through the body and proliferate after they are first removed, altered, expanded in number and, finally, returned to a patient's body.
