Open Access research that helps to deliver "better medicines"...

Strathprints makes available scholarly Open Access content by the Strathclyde Institute of Pharmacy and Biomedical Sciences (SIPBS), a major research centre in Scotland and amongst the UK's top schools of pharmacy.

Research at SIPBS includes the "New medicines", "Better medicines" and "Better use of medicines" research groups. Together their research explores multidisciplinary approaches to improve understanding of fundamental bioscience and identify novel therapeutic targets with the aim of developing therapeutic interventions, investigation of the development and manufacture of drug substances and products, and harnessing Scotland's rich health informatics datasets to inform stratified medicine approaches and investigate the impact of public health interventions.

Abstract

Thin films of the metallopolymer [Os(bpy)2 (PVP)10] 2+, where bpy is 2,21-dipyridyl and PVP is poly(4-vinylpyridine), luminesce at 750±12 nm upon excitation at 355nm. The luminescence decay responses can be described by a double exponential decay model in which the limiting lifetimes are 75±14 (population fraction of 0.9) and 35±8 ns (population fraction of 0.1) for films in contact with aqueous 0.1 M H2SO4- Electrochemistry has been used to create well defined concentrations of the luminescence quencher, Os 3+, within the films. Time resolved spectroscopy reveals that both dynamic and static processes contribute to luminescence quenching with a rate constant for electron transfer between the photoexcited Os2+* and the Os3+ centres of 1.3×107 M-1s -1 being observed. Stable gold nanoparticles have been created within the metal lopolymer by the chemical reduction of tetrachloroaurate. These nanocomposite materials exhibit enhanced emission intensity compared to the gold free films.
