Multiphoton laser techniques might allow scientists to target the aggregations of proteins in the brain linked to diseases such as Alzheimer's and Parkinson's, according to researchers from Chalmers University of Technology in Sweden and the Polish Wroclaw University of Technology. Treating the malfunctioning proteins remains a challenge, but scientists are hopeful that photo acoustic therapy could provide an alternative approach for brain diseases. Details of the study are published in the journal Nature Photonics.
