碱性染料浓缩的纳米颗粒（直径类似于33 nm）通过单光子和双光子激发显示基于荧光的比率pH响应，通过纳米级颗粒内能量转移具有改善的质子感测能力（pK（a）类似于6.4）。
Basic dye-concentrated nanoparticles (similar to 33 nm in diameter) show fluorescence-based ratiometric pH response, by one- and two-photon excitations, with improved proton sensing ability (pK(a)similar to 6.4) through nanoscopic intraparticle energy transfer.
