Correlation between human health and reactive oxygen species produced in blood: a long-term chemiluminescence and fluorescence analysis

Abstract The previous slide-glass type system could simultaneously detect reactive and highly reactive oxygen species, i.e., superoxide radicals (O2 −·) and hypochlorite ions (OCl−) elicited from leucocytes in sample blood, but had some drawbacks, i.e., signal noise from air-flow stirring, potential...
