New Technique for Detection of Carbon Nanotubes in the Body
New research being conducted at the University of Arkansas is demonstrating that Raman spectroscopy can be used to detect and monitor circulating carbon nanotubes in vivo and in real time.
New research being conducted at the University of Arkansas (Fayetteville, Arkansas) is demonstrating that Raman spectroscopy can be used to detect and monitor circulating carbon nanotubes in vivo and in real time.
Carbon nanotubes can be used for various advanced biomedical applications that would allow researchers to improve their understanding of how nanomaterials interact with living biological systems. Biodistribution of carbon nanotubes, which until now has been monitored only by collecting samples after various time intervals, could now be monitored while the animal is alive.
This research is significant because it can be used to detect circulating cancer cells that have been tagged by carbon nanotubes.
Raman Spectroscopy Aflatoxin Detection Enhances Peanut Safety
March 11th 2025A research team from Jiangsu University has developed a Raman spectroscopy-based method to detect aflatoxin B1 (AFB1) in peanuts with improved accuracy and efficiency. By employing a two-step hybrid strategy integrating backward interval partial least squares (BiPLS) and variable combination population analysis (VCPA), the new model significantly enhances the precision of AFB1 detection, providing a more reliable approach for food safety monitoring.
Nanometer-Scale Studies Using Tip Enhanced Raman Spectroscopy
February 8th 2013Volker Deckert, the winner of the 2013 Charles Mann Award, is advancing the use of tip enhanced Raman spectroscopy (TERS) to push the lateral resolution of vibrational spectroscopy well below the Abbe limit, to achieve single-molecule sensitivity. Because the tip can be moved with sub-nanometer precision, structural information with unmatched spatial resolution can be achieved without the need of specific labels.
Transforming Connectivity with a Comprehensive Review of IoT Sensors
March 3rd 2025A recent review by researchers at Nagpur University and Seth Kesarimal Porwal College explores the ever advancing landscape of the Internet of Things (IoT) and its essential components—sensors and actuators. The review paper classifies various IoT sensors and examines their role in integrating the physical and digital worlds to enable smarter devices and enhanced automation.
