Laser technology is pushing the boundaries of cryo-electron tomography (cryo-ET). A new study shows how femtosecond lasers may dramatically improve image contrast in biological molecule imaging.<\/p>\n
Cryo-ET faces a key limitation: biological molecules interact weakly with electrons, leading to low-contrast images. The new approach uses laser-assisted preparation to enhance sample contrast.<\/p>\n
Meanwhile, Lawrence Livermore National Laboratory reported a breakthrough in metalens technology that splits a femtosecond laser into over 120,000 coordinated focal spots, enabling parallel writing across centimeter-scale areas.<\/p>\n
The laser confocal microscopes market is also expected to grow significantly through 2032, with Asia-Pacific showing the fastest growth.<\/p>\n
