MIT chemists have developed a new stable red fluorescent dye based on borenium ions that emit in the near-infrared range, potentially enabling clearer biomedical imaging of deep tissues and tumors, with applications in temperature sensing and optoelectronics.
Researchers from Trinity College Dublin and the Royal College of Surgeons in Ireland have developed innovative fluorescent dyes that change color to visualize different biological environments within cells, enabling real-time, high-contrast imaging of cellular processes. These dyes, capable of "switching on" and "off" based on their location within cellular structures, have potential applications in bio-sensing, drug delivery imaging, and the study of cellular dynamics, with implications for advancements in medicine and biology. The breakthrough, published in the journal Chem, was made possible through international collaboration and significant funding from Irish research bodies.
Researchers have developed a new imaging technique using fluorescent dyes and laser microscopes to capture the most detailed images of human embryos developing in real time. This non-invasive method allows for the study of crucial events in the early stages of development without genetically altering the embryos. The technique could have applications in non-invasive screening of embryos conceived through in vitro fertilization (IVF) and may provide insights into chromosomal abnormalities and variations in embryonic development between humans and mice. The researchers hope to further improve the imaging process and potentially use it in clinical settings to determine the viability of embryos before implantation.
