Molecular tools to generate reactive oxygen species in biological systems

Bioconjugate Chemistry 2019 April 15
Reactive oxygen species (ROS) not only are by-products of aerobic respiration, but also play vital roles in metabolism regulation and signal transductions. It is important to understand the functions of ROS in biological systems. In addition, scientists have made use of ROS to kill bacteria and tumors through a process known as photodynamic therapy (PDT). This paper provides a concise review of current molecular tools that can generate ROS in biological systems via either non-genetic or genetically-encoded way. Challenges and perspectives are further discussed with the hope of broadening the applications of ROS generators in research and clinical settings.

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase
