Topographical Gel Nanosensors

Authors: George Rajna

In a new study, Karthik Pushpavanam and an interdisciplinary team of researchers in the departments of Chemical Engineering, Molecular Sciences, Banner MD Anderson Cancer Center and Arizona Veterinary Oncology in the U.S. has described a novel gel-based nanosensor. The technology allows colorimetric detection and quantification of topographical radiation dose profiles during radiotherapy. [28] Nanometers are one billionth of a meter, a metric typically used to measure molecules and scientific building blocks not visible to the human eye. [27] A new chip-based platform developed by researchers at UC Santa Cruz integrates nanopores and optofluidic technology with a feedback-control circuit to enable an unprecedented level of control over individual molecules and particles on a chip for high-throughput analysis. [26] The ability to observe how life works at a nanoscale level is a grand challenge of our time. [25] Scientists at the Max Planck Institute for Plant Breeding Research in Cologne have now discovered how a protein called LMI1 can control leaf growth and shape. [24] One way we might actually prove our biological complexity is to look at the number of different proteins that our bodies can produce for building all our different types of cells and the other things they need. [23] A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions.
