Cores from the northern end of the transect, which experienced
longer oxygen exposure times, were more decomposed than cores from the south, which formed under warmer temperatures.
The addition of this pendant catalyst created an MnP - PVPON / TA capsule with the following characteristics: 1) the microcapsules synergistically remove reactive
oxygen species, including superoxide and hydrogen peroxide, at dramatically increased rates compared to unmodified TA / PVPON microcapsules; 2) the microcapsule does not degrade with
long exposure to reactive
oxygen species; and 3) the microcapsules are nontoxic to mouse splenocytes.
