Handheld medical laser device uses 1270 nm laser diode from SemiNex

A handheld laser device that features a 1270 nm laser diode from SemiNex (Peabody, MA), developed in collaboration with Veralase (Middleton, MA) and Massachusetts General Hospital (Boston, MA), has been shown to enhance immune response to vaccines. This near-infrared laser treatment avoids side effects like soreness, inflammation, erythema, and tissue damage that often occurs with chemical adjuvants. 1270 nm irradiation in water causes photoactivation in the ground state of oxygen to create singlet oxygen, which is a high-energy form of oxygen that can be used in preparative organic chemistry and photodynamic therapy.
