Bioactive near-infrared II clusters for 3D imaging and acute inflammation inhibition
The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method......»»
Studies find China-based emissions of three potent climate-warming greenhouse gases have spiked in past decade
When it comes to heating up the planet, not all greenhouse gases are created equal. They vary widely in their global warming potential (GWP), a measure of how much infrared thermal radiation a greenhouse gas would absorb over a given time frame once.....»»
New technique to diagnose cancer metastasis uses origami nanoprobes
Johns Hopkins engineers have created a new optical tool that could improve cancer imaging. Their approach, called SPECTRA, uses tiny nanoprobes that light up when they attach to aggressive cancer cells, helping clinicians distinguish between localize.....»»
