Thiolaryl substituted β-lactams as important capping agents for hafnia nanoparticles.

A new study on the synthesis of β-lactams functionalized hafnia nanoparticles is done. The reported work describes the utility of hydrothermal method to prepare hafnia nanoparticles coated with β-lactams. The method provides spherical NPs with dimensions of 30–50 nm and are slightly anionic. The conjugate has been found to be biologically active and well characterized by techniques like FTIR, XRD, FESEM, TEM, and EDX methods. The methodology gives a conjugate whose synthesis has not been attempted so far in the literature. [ABSTRACT FROM AUTHOR]
