Abstract

Radiolabelling, magnetic and fluorescent properties are incorporated in one single Fe3O4@HA nanoparticle with potential application as trimodal probes., Magnetic and fluorescent hydroxyapatite nanoparticles were synthesised using Al(OH)3-stabilised MnFe2O4 or Fe3O4 nanoparticles as precursors. They were readily and efficiently radiolabelled with 18F. Bisphosphonate polyethylene glycol polymers were utilised to endow the nanoparticles with excellent colloidal stability in water and to incorporate cyclam for high affinity labelling with 64Cu.

Abstract

The last glacial period was characterized by centennial-millennial scale climatic instabilities, which involved rapid changes in oceanographic conditions and in atmospheric temperature over different continental regions of the Northern Hemisphere. These Dansgaard-Oeschger cycles, which are most pronounced between 20-60 kyr BP, are a prominent feature in ice core and marine records, but have only rarely been documented from terrestrial records. Several hypotheses have been brought forward to explain the observed fluctuations, but understanding the relationship between different mechanisms is hampered by large dating uncertainties and insufficient sampling resolution to perform detailed correlations between different archives. One of the few European terrestrial sequences, with adequate sedimentation rates to record this rapid climate variability is the site Les Echets (45°54'N; 4°56'E) in south-central France. The strategic location of the site, south of the large ice sheets, at some distance from the North Atlantic and north of the Mediterranean region, fills an important gap in determining the spatial vari¬ability and environmental impact of these fluctuations. New sediment cores were obtained at Les Echets in autumn 2001 and are currently analysed for a variety of different climatic and environmental proxies (tephra, mineral magnetics, grain-size, LOI, carbonates, C/N ratio, δ13C, δ15N, δ18O, biogenic silica, biomarkers, pollen, macrofossils, charcoal, chironomids, diatoms, ostracods).
