The paper attempts to develop a nanocore-shell structure with photomagnetic nature, and let it undergo conjugation reaction with the DNAs of different sequences in order to apply the structure to target-based drug therapy and biomedical-related areas. First of all, iron platinum (FePt) magnetic nanofluid with average particle size 20 nm is prepared by chemical method. After that, zinc sulfide with...
Nanosized ZnS passivated by chitosan was successfully synthesized by coordination transformation method through solution route (chitosan-Zn2+ complex solution co-precipitated with Na2S solution) and film route (chitosan-Zn2+ complex film immersed in Na2S solution). UV absorption of nanosized ZnS showed a clear blue-shift of the onset wavelength for both kinds of the samples while the shift amount...
Recent advancements in nanomaterials have produced a new class of fluorescent labels based on the semiconductor quantum dots. The emission wavelength of quantum dots can be continuously tuned by changing the particle size or component, and a single light source can be used for simultaneous excitation of all dots with different band gaps. High-quality dots are also highly stable against photobleaching...
