A composite particle that includes: a fluorescent semiconductor core/shell nanoparticle (preferably, nanocrystal); and a malonic acid derivative attached to the core/shell nanoparticle outer surface, wherein the malonic acid derivative (prior to attachment to the nanoparticle) has the following Formula (I): wherein: R
1
is a linear or branched alkyl group having 8 or more carbon atoms, or a linear or branched alkylene group having 8 or more carbon atoms (wherein it is understood that C—R
1
is a single or double bond); R
2
is H or a linear or branched alkyl group having 1 or more carbon atoms; and x is 0 (resulting in C═R
1
) or 1 (resulting in C—R
1
); and wherein the malonic acid derivative is liquid at room temperature (prior to attachment to the nanoparticle).
