Plasmonic Surface Modifications with Hard-Core/Soft-Shell Nanoparticles
… functionalities are introduced by plasmonic nanoparticles and tailored either via the deposition or via chemical post-modification. The colloid types, which are used in this framework, are hard-core/soft-shell colloids. An advantage of such hybrid particles is the plurality in functionalities. …

Hybrids Based on Layered Silicates
Novel hybrid nanoparticles were synthesized based on combinations of various layered silicates as inorganic core and well-defined polymer chains as a shell. In all cases positively charged 2-(dimethylamino)ethyl methacrylate (DMAEMA) was incorporated into the polymeric structure to serve as a firm …

Genetic Recombination in Pneumococcal Transformation: The Role of Integrity and Heterogeneity of Deoxyribonucleate Molecules, as Reflected in Kinetic Analysis
… of the particular markers and the number of DNA particles involved, thus singly-marked transformants accumulate linearly with time of exposure to DNA, as do some multiply-marked transformants. Other unlinked pairs of markers accumulate exponentially with time, by a second-order process, at a rate …
