Carbohydr Polym. 2016 Jan 20:136:1323-31. doi: 10.1016/j.carbpol.2015.10.032. Epub 2015 Oct 22.

Abstract

New biopolymeric nanoparticles consisting of cellulose nanowhisker (CNW) as support system and polyglycerol (PG) as surface modifying agent were prepared. PG was attached to the surface of CNW by click chemistry reaction. CdSe quantum dots then interact with the prepared system by noncovalent interaction. These new synthesized biopolymeric nanoparticles were characterized by spectroscopic measurement methods such as IR spectroscopy, UV-vis spectroscopy, NMR spectroscopy; scanning electron microscopy etc. due to the presence of hydrophilic polymerr at the surface of CNW, synthesized nanomaterials were water soluble, and have a large number of functional group for further modification. Also the presence of fluorescence quantum dots (QDS) caused fluorescence property of synthesized system. These new synthesized system has potential application to be used in different filed such as drug delivery, biomedical imaging etc.
