DOI: 10.1002/jbio.202100158
Abstract: Multiphoton microscopies using short-wave infrared (SWIR) radiation offer nondestructive and high resolution imaging through tissue. Two-photon fluorescence, for example, is commonly employed to increase the penetration depth and spatial resolution of SWIR imaging, but the… read more here.
