Abstract: | The formation of supramolecular structures, assemblies, and arrays held together by weak intermolecular interactions and non-covalent
binding mimicking natural processes has been used in applications being anticipated in nanotechnology, biotechnology and the
emerging field of nanomedicine. Encapsulation of C60 fullerene by cyclic molecules like cyclodextrins and calixarenes has potential for a number of applications. Similarly, biomolecules
like lysozyme also have been shown to encapsulate C60 fullerene. This poster article reports the recent trends and the results obtained in the nanoencapsulation of fullerenes
by biomolecules containing nonpolar cavities. Lysozyme was chosen as the model biomolecule and it was observed that there
is no covalent bond formed between the bimolecule and the C60 fullerene. This was confirmed from fluorescence energy transfer studies. UV–Vis studies further supported this observation
that it is possible to selectively remove the C60 fullerene from the nonpolar cavity. This behavior has potential in biomedical applications |
