Claims20
A nanoparticle comprising a carbon matrix and one or more moieties present on the surface of the carbon matrix, wherein the one or more moieties is selected from the group consisting of —CO2H and —C(═O)NH(CH2CH2O)nCH2CH2NHR, wherein n is a whole number selected from 3-100 and R is a hydrogen or a targeting group;
- and the carbon matrix comprises a compound of Formula I:
- wherein, M is a metal selected from the group consisting of Co, Ni, Mn, Zn, Pt, and Pd;
- or M represents two hydrogen, each of which is covalently bound to a nitrogen;
- and
- represents a covalent nitrogen-carbon bond between the compound of Formula I and the carbon matrix.
