ABSTRACT
This chapter provides an introduction to light-water research with
an emphasis on theories related to laser photobiomodulation (PBM),
also known as low-level laser therapy (LLLT), and their potential
clinical application. Light-water interactions are at the core of
molecular and metabolic mechanisms that coexist with and can
complement and/or substitute for the classic PBM respiratory and
electron transport pathway primarily associated with cytochrome c
oxidase (Cox) (Complex IV). Nevertheless, until now, there had been
a complete dearth of information in PBM textbooks about this topic
and its progress over the last decades.
