The aim of this study was to develop hepatocyte-targeting non-viral polymeric nono-carriers for gene delivery. Chitosan was selected as the main polymer. An asialoglycoprotein receptor recognized sugar, galactose, was introduced.

All the synthesized compounds were characterized by spectral studies and screened for their in vitro antibacterial activity against S. aureus and B. thuringiensis (gram positive), and E. coli and K. pneumoniae (gram negative) bacterial strains. On comparing with the standard drug gentamicin, compounds derived from 4-methoxy and 3,4,5-trimethoxy benzaldehyde, i.e. 5g and 5h, showed broad spectrum antibacterial activity and the remaining compounds showed weak to moderate activity.

In this study nanocomposite materials thin films based on poly [2-methoxy-5-(2’-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) and nanocrystalline TiO2 (nc-TiO2) have been fabricated. The photoluminescence (PL) spectra of pure MEH-PPV and nanohybrid films have shown that the excitation at a 377 nm wavelength leads to the strongly enhanced performance in photoluminescent intensity due to the compositions of TiO2 component.

In this work, we have studied the photoluminescence (PL) quenching of two polymeric composites, poly[2- methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) and poly(3-hexylthiophene) (P3HT) in presence of nc-TiO2 particles by PL- spectroscopy. PL quenching values are 19.2% and 45.5%, for MEH-PPV+nc-TiO2 and P3HT+nc-TiO2, respectively.
