Hybrid microspheres with a polystyrene core coated with magnetite nanoparticles were prepared by two techniques. Firstly, monodispersed functional polystyrene latex particles were prepared by emulsion polymerization. In a general way chemical groups may be introduced through polymerizable surfactant or functional monomer. Magnetite acidic or alkaline sol was added in, then magnetite nanoparticles were absorbed onto latex particles by electrostatic attraction and core-shell composite particles were formed. Secondly, core-shell composite particles were prepared by miniemulsion polymerization. To modify the tendency of conglomeration of magnetite and increase the amount of magnetic particles onto the composite particles, silane coupling agent MPS was used as surface modification agent for magnetite. A series of different size and coating morphology magnetic hybrid particles were prepared through the adjustment of some experiment parameters. The obtained functional core-shell particles were characterized by FTIR, TEM, etc.

Linear Polyethylenimine

We developed a core–shell polyplex with minimal high generation dendrimer to condense DNA and low-molecular-weight linear polyethylenimine coated on the core. The polyplex represented both high transfection efficacy and low toxicity.

The earliest account of the contamination of electron microscope specimens by the deposition of carbonaceous material during electron irradiation was published in 1947 by Watson who was then working in Canada. It was soon established that this carbonaceous material is formed from organic vapours, and it is now recognized that the principal source is the oil-sealed rotary pumps which provide the backing vacuum. It has been shown that the organic vapours consist of low molecular weight fragments of oil molecules which have been degraded at hot spots produced by friction between the vanes and the surfaces on which they slide. As satisfactory oil-free pumps are unavailable, it is standard electron microscope practice to reduce the partial pressure of organic vapours in the microscope in the vicinity of the specimen by using liquid-nitrogen cooled anti-contamination devices. Traps of this type are sufficient to reduce the contamination rate to about 0.1 Å per min, which is tolerable for many investigations.
