The current study was aimed to design a thiolated chitosan (TC) based mucoadhesive nanoparticle (NP) formulation for enhancing the oral bioavailability of an anti-coagulant, Ticagrelor (TG). Nanoparticles (NPs) containing naturally occurring biodegradable polymers have been revealed as promising carriers controlled delivery various therapeutic agents through route. Ionic gelation technique adop...

Thermal interface conductance was measured for soluble gold nanorods (NRs) coated with mercaptocarboxylic acids (HS-(CH(2))(n)COOH, n = 5, 10, 15), thiolated polyethylene glycols (MW = 356, 1000, 5000), and HS-(CH(2))(15)-COOH-coated NRs further coated with alternating layers of poly(diallyldimethylammonium chloride) and poly(sodium styrenesulfonate). Ferguson analysis determined ligand thickne...

We have designed a heterofunctionalized nanoparticle conjugate consisting of a 13-nm gold nanoparticle (Au NP) containing both antisense oligonucleotides and synthetic peptides. The synthesis of this conjugate is accomplished by mixing thiolated oligonucleotides and cysteine-terminated peptides with gold nanoparticles in the presence of salt, which screens interactions between biomolecules, yie...

We demonstrate a new approach to synthesize several unique nanostructures by tuning the selective reactivities on individual symmetry-breaking segmented selenium nanorods (SBS-SeNRs). The segment-selective reactions from thiolated silane endowed the formation of float-like SBS-SeNR@SiO2 with a silica coating on the t-Se segment. Several other unique nanostructures were further synthesized by ap...

A series of mucoadhesive disks with celecoxib as a model drug of very low aqueous solubility were prepared and characterized. Two polymers of polyaspartamide type, poly[alpha,beta-(N-2-hydroxyethyl-DL-aspartamide)] (PHEA, 1) and its thiolated analogue poly[alpha,beta-(N-2-hydroxyethyl-DL-aspartamide)]-poly[alpha,beta-(N-2-thioethyl-DL-aspartamide)] copolymer (PHTA, 2a,b), and two commercially a...

We describe an environmentally friendly, top-down approach to the synthesis of Au89Fe11 nanoparticles (NPs). The plasmonic response of the gold moiety and the magnetism of the iron moiety coexist in the Au89Fe11 nanoalloy with strong modification compared to single element NPs, revealing a non-linear surface plasmon resonance dependence on the iron fraction and a transition from paramagnetic to...

We present electronic transport measurements through thiolated C60 molecules in liquid environment. The molecules were placed within a mechanically controllable break junction using a single anchoring group per molecule. When varying the electrode separation of the C60-modified junctions, we observed a peak in the conductance traces. The shape of the curves is strongly influenced by the environ...
