Hybrid polymer micelles capable of cRGD targeting and pH-triggered surface charge conversion for tumor selective accumulation and promoted uptake
This study presents both tumor-targeting ligands (cRGD) and pH-activated surface charge-conversional moiety (imidazole) decorated micelles for Dox delivery. cRGD is expected to induce preferential tumor accumulation, while imidazole switches on positive charge in a tumor acid environment, which leads to enhanced micel…
Identification of adsorbed molecules via STM tip manipulation: CO, H 2 O, and O 2 on TiO 2 anatase (101)
While Scanning Tunneling Microscopy (STM) has evolved as an ideal tool to study surface chemistry at the atomic scale, the identification of adsorbed species is often not straightforward. This paper describes a way to reliably identify H2O, CO and O2 on the TiO2 anatase (101) surface with STM. These molecules are of a…
Spray processing of TiO2 nanoparticle/ionomer coatings on carbon nanotube scaffolds for solid-state supercapacitors
A one-step scalable spray technique was used to fabricate solid-state supercapacitors with multi-wall carbon nanotube/TiO2-nanoparticle/ionomer hybrid electrodes. The 3D electrode nanostructure was designed for mobile H+ ion generation and fast electron-ion dual conduction, achieving an unusual and highly attractive b…
Effect of Calcination Temperature on La0.7Sr0.3MnO3 Nanoparticles Synthesized with Modified Sol-gel Route
We report a modified route to synthesize La0.7Sr0.3MnO3 nanoparticle with oxalic acid as chelating agent and oleic acid as surfactant at different calcination temperatures. The synthesized nanoparticles were characterized using XRD, SEM, FTIR and VSM. XRD confirms the formation of phase pure perovskite structure with…

Internal and external morphology-dependent plasmonic resonance in monolithic nanoporous gold nanoparticles
We report morphology-dependent plasmonic resonance in monolithic nanoporous gold nanoparticles with a nanoscale internal porous network produced by the combination of lithographic patterning and dealloying.
Galactosylated reduction and pH dual-responsive triblock terpolymer Gal-PEEP-a-PCL-ss-PDMAEMA: a multifunctional carrier for the targeted and simultaneous delivery of doxorubicin and DNA
A multifunctional bioreducible system based on galactosamine-modified PEEP- <italic>a</italic> -PCL- <italic>ss</italic> -PDMAEMA has been prepared and used for the targeted co-delivery of doxorubicin and DNA.
Tamoxifen embedded in lipid bilayer improves the oncotarget of liposomal daunorubicin in vivo
The objective of this research is to investigate the plasma pharmacokinetics and bio-distribution of liposomal daunorubicin plus tamoxifen in breast cancer murine models through intravenous administration. Daunorubicin and tamoxifen plasma levels in pharmacokinetics studies were determined using HPLC. Biodistributions…
Conjugation versus rotation: good conjugation weakens the aggregation-induced emission effect of siloles
Incorporation of polycyclic aromatic hydrocarbons into siloles enhances their light emission in solutions but lowers emission efficiency in the aggregated state. The competitive interaction between conjugation and rotation is thus studied.
Energy transfer mechanism in Er3+ doped fluoride glass sensitized by Tm3+ or Ho3+ for 2.7-\mu m emission
Enhanced 2.7 m emission is obtained in Er 3+ /Tm 3+ and Er 3+ /Ho 3+ codoped ZBYA glasses. Absorption and emission spectra are tested to characterize the 2.7 m emission properties of Er 3+ /Tm 3+ and Er 3+ /Ho 3+ doped ZBYA glasses and a reasonable energy transfer mechanism of 2.7 m emission between Er 3+ and Tm 3+ Ho…
