In their paper published in the journal <i>Nature Photonics<\/i>, the group describes their study of amyloid fibrils and plaques in mice and humans and what they found.<\/p>\n<p>Amyloid fibrils are tiny structures that self-form in some proteins. When they clump together, they form what are known as <a href=\"https:\/\/phys.org\/tags\/amyloid\/\" rel=\"tag\" class=\"\">amyloid<\/a> plaques. They are associated with the development of neurological diseases such as Alzheimer\u2019s and Parkinson\u2019s disease. Despite years of study, it is still not known what causes them. In this new effort, the researchers sought to learn more about the early stages of fibril development by developing a way to see it happening.<\/p>\n<p>Prior work had shown that when ultraviolet light shines onto tissue-containing proteins, the tissue emits blue light. Researchers have found that the emissions become stronger if there are fibrils present in the proteins. While this finding has been useful, it has only allowed for superficial study of <a href=\"https:\/\/phys.org\/tags\/fibril\/\" rel=\"tag\" class=\"\">fibril<\/a> formation due to the shallow depth of UV and <a href=\"https:\/\/phys.org\/tags\/blue+light\/\" rel=\"tag\" class=\"\">blue light<\/a> penetration. In their experiments, the researchers tried firing near-field radiation at sample human proteins and found that and fibrils present would emit a dim, near-infrared signal. This was important, because unlike UV light, near-field radiation can penetrate relatively deeply into tissue.<\/p>\n<p><a href=\"https:\/\/phys.org\/news\/2019-05-amyloid-fibrils-lit-near-infrared-emit.html\" target=\"_blank\" rel=\"noopener noreferrer\"><\/p>\n<div style=\"clear:both;\">Read more<\/div>\n<p><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team of researchers affiliated with several institutions in France has found that amyloid fibrils lit with near-infrared radiation emit a dim, near-infrared signal.
