“ Cr(III) and Cr(VI) have different binding capacity with sparfloxacin , and have different combination modes with calf thymus DNA.”
“The result shows that Cr(III) has weaker binding capacity to SPFX in the SPFX-Cr(III) binary system, but influences the binding between SPFX and DNA obviously in SPFX-DNA-Cr(III) ternary system.”
