Injectable polymer microsphere-based stem cell delivery systems have a severe problem that they do not offer desirable environment for adhesion, proliferation, and differentiation because it is difficult to entrap large number of hydrophilic functional protein molecules into the core hydrophobic microspheres. In this work, soybean lecithin (SL) applied bone morphogenic protein-2 (BMP-2) nanoporous poly(lactide-co-glycolide) (PLGA)-based microspheres by two-step method: SL/BMP-2 complexes...
The solubility of single-walled carbon nanotube (SWCNT) polyelectrolytes [K(THF)]nSWCNT in dimethyl sulfoxide (DMSO) was determined by a combination centrifugation, UV-vis spectral properties, and solution extraction. SWCNT formed liquid crystal at concentration above 3.8 mg/mL. Also, crown ether 18-crown-6 found to increase the DMSO. Raman spectroscopy near-infrared (NIR) fluorescence analyses were applied study functionalization SWCNTs. Small-diameter SWCNTs be preferentially...
In this work, single-walled carbon nanotube (SWCNT) fibers were produced from SWCNT polyelectrolyte dispersions stabilized by crown ether in dimethyl sulfoxide and coagulated into aqueous solutions. The had concentrations up to 52 mg/mL showed liquid crystalline behavior under polarized optical microscopy. are neat (i.e., not forming composites with polymers) a tensile strength 124 MPa Young's modulus of 14 GPa. This is comparable those spun strong acids. Conductivities on the order 104 S/m...
Abstract In this work, a novel colorimetric strategy for miRNA analysis is proposed based on hybridization chain reaction (HCR)-mediated localized surface plasmon resonance (LSPR) variation of silver nanoparticles (AgNPs). in the sample to be tested able release HCR initiator from solid interface AgNPs colloid system by toehold exchange-mediated strand displacement, which then triggers consumption fuel strands with single-stranded tails HCR. The final produced long nicked double-stranded DNA...
In this review, we systematically describe the state-of-knowledge in area of carbon nanotubides (CNTDs). CNTDs can be used for achieving highly concentrated dispersions SWCNTs and also as an important intermediate covalent chemical modification. recent years, researchers have SWCNTDs starting materials functionalization with functionalities such alkyl chains, carboxylic acids, sulfide, amino, hydroxyl, silyl, bromide, ethers, ketones polymers. Also, discussed observed selectivity on towards...
Electrospun PI-<italic>co</italic>-PBO nanofiber belts possessed superior thermomechanical properties.
The use of photoluminescent probes for differentiating free amino acids from biomolecules containing the same is challenging. Photoluminescent generally present similar emission spectra when in presence either free-amino or protein those acids. Probes based on cyclometalated iridium(III) complexes Ir(L)2(sol)2 (where L 2-phenylpyridine, 2-(2,4-difluorophenyl)pyridine, benzo[h]quinolone, and sol a solvent molecule) long-lived bound to histidine. This tuned by microenvironment around complex...
Cationic ruthenium(II) polypyridyl complexes with appended pyrene groups have been synthesized and used to disperse single-walled carbon nanotubes (SWCNT) in aqueous solutions. To this end, planar enable association by means of π-stacking onto and, turn, the attachment cationic ruthenium complexes. Importantly, ionic nature allows formation stable dispersions featuring individualized SWCNTs water as confirmed a number spectroscopic microscopic assays. In addition, steady-state...
Graphenide solutions in NMP have been prepared by dispersing potassium intercalated graphite with the assistance of 18-crown-6. The highest graphenide solubility achieved is 1.5 mg mL-1. applied to spin graphene/SWCNT hybrid fibers.
To effectively address fundamental problems in using transition metal oxides as high-performance anode materials for lithium ion batteries (LIBs), we prepare Co 3 O 4 QDs@SWCNT heterostructures composed of well-dispersed ultrafine cobalt oxide (Co ) encapsulated within flexible sheet-like single-walled carbon nanotubes (SWCNTs) matrix the first time, through a facile and controllable method via evaporation-induced self-assembly (EISA) nanotubides (SWCNTDs). By varying loading amount content...
