Although the optical transitions in lanthanide-doped nanoparticles essentially resemble those in bulk materials, the nanostructure amenable to surface modifications provides new opportunities for research.
32.
These nanoparticles were synthesized by selective surface modification with one hemisphere exhibiting high binding affinity for human endothelial cells and the other hemisphere being resistant towards cell binding.
33.
Stewart & Nimmo ( 2002 ) find it is extremely unlikely that CO 2 clathrate is present in the Martian regolith in quantities that would affect surface modification processes.
34.
Although many surface modifications are not permanent on PDMS due to its relatively high chain mobility compared with polymers, PDMS still remains relevant as a material for microfluidic applications.
35.
Thermoplastic polyethylene and polypropylene treated with brief oxygen plasma exposure have seen contact angles as low as 22? and the resulting surface modification can last years with proper packaging.
36.
Surface modification involves the fundamentals of physicochemical interactions between the biomaterial and the physiological environment at the molecular, cellular and tissue levels ( reduce bacterial adhesion, promote cell adhesion ).
37.
"' Black silicon "'is a semiconductor material, a surface modification of silicon with very low reflectivity and correspondingly high absorption of visible ( and infrared ) light.
38.
Protein surface modification of various types biomaterials ( ceramics, polymers, metals, composites ) is performed to ultimately increase biocompatibility of the material and interact as a bioactive material for specific applications.
39.
Because of their high mechanical, thermal and chemical stability, variable manufacturing of pore sizes with a small pore size distribution and variety of surface modifications, a wide array of applications are possible.
40.
The conventional approaches such as use of permeation enhancers, surface modification, prodrug synthesis, complex formation and colloidal lipid carrier based strategies have been developed for the delivery of drugs to intestinal lymphatics.
