An efficient electrocatalytic functionalization of N-arylglycine esters is reported. The protocol proceeds in an undivided cell under constant current conditions employing the simple, cheap and readily available n-Bu4NI as the mediator. In addition, it is demonstrated that the mediated process is superior to the direct electrochemical functionalization.

Cyclodextrin poly-functionalization has fueled progress in their use multiple applications such as enzyme mimicry, but also the polymer sciences, luminescence, sensors or for biomedical applications. However, regioselective access to a given pattern of functions on β-cyclodextrin is still very limited. We uncover new orienting group, thioacetate, that expands toolbox available cyclodextrin poly...

objective(s): carbon nanotube (cnt) has been widely applied at molecular and cellular levels due to its exceptional properties. studies based on conjugation of cnts with biological molecules indicated that biological activity is preserved. polyethylenimine (pei) is explored in designing novel gene delivery vectors due to its ability to condense plasmid dna through electrostatic attraction. in t...

synthesis and characterization of two functionalized gold nanoparticles by using of two poly functional amino acids (l-arginine and l-aspartic acid) are reported. the gold nanoparticles were reduced by sodium citrate and functionalized with l-arginine at the ph of 7 and 11 and l-aspartic acid at the ph of 7. transmission electron microscopy, uv-vis spectroscopy, dynamic light scattering, zeta p...

the present study deals with the synthesis andfunctionalization of mesoporous silica nanoparticles as drug delivery platforms. sba-15 nanorods with high surface area (1010 m2g-1) were functionalized by post grafting method using 3-mercaptopropyl trimethoxysilane (mpts). the parent and thiol-functionalized sba-15 nanorods were used as nanocarriers for an anticancer drug (gemcitabine). the charac...

Single-stranded DNA (ssDNA) with repetitive sequence was demonstrated to be a versatile nanotemplate for introducing biological activity in a self-assembled manner. Re-functionalization and rejuvenation of the ssDNA nanotemplate were achieved under mild biological conditions without using high temperature and strong alkaline treatment to denature DNA.
