Modulation Of Enzyme-Substrate Selectivity Using Tetraethylene Glycol Functionalized Gold Nanoparticles, Bj Jordan, R Hong, G Han, S Rana, Vm Rotello
Vincent Rotello
Tetraethylene glycol (TEG) functionalized gold nanoparticles with 2 nm core diameters (AuTEG) enhance α-chymotrypsin (ChT) enzyme activity in a substrate-selective fashion. We explored the hydrolysis of four different substrates and observed a marked increase in activity with the most hydrophobic substrate N-succinyl-alanine-alanine-proline-phenylalanine- p-nitroanilide (TP), while the other substrates remain virtually unaffected by the AuTEG 'crowding effect' in solution. The enhancement in catalysis is indicated by an increase in Kcat/Km as obtained from Lineweaver–Burk analysis and we hypothesize it to arise from a macromolecular crowding effect analogous to that observed with high molecular weight poly(ethylene glycol) (PEG) polymers.

Vincent Rotello
A study of the in vitro nanoparticle-templated assembly of a mutant of cowpea chlorotic mottle virus lacking most of the N-terminal domain (residues 4-37), NDelta34, is presented. Mutant empty proteins assemble into empty capsids with a much broader distribution of sizes than the wild-type virus. This increased flexibility in the assembly outcomes is known to be detrimental for the assembly process in the presence of molecular polyanions. However, when rigid polyanionic cores are used, such as nanoparticles, the assembly process is restored and virus-like particles form. Moreover, the breadth of the nanoparticle-templated capsid size distribution becomes comparable with the wild-type …

Formation And Size Tuning Of Colloidal Microcapsules Via Host-Guest Molecular Recognition At The Liquid-Liquid Interface, D Patra, F Ozdemir, Or Miranda, B Samanta, A Sanyal, Vm Rotello
Vincent Rotello
Stimuli-responsive colloidal microcapsules have been fabricated at the oil−water interface using molecular recognition between functionalized gold nanoparticles. Water-soluble β-cyclodextrin-capped gold nanoparticles and organo-soluble adamantyl-functionalized gold nanoparticles are self-assembled at the water−toluene interface via specific host−guest molecular interactions to provide robust microcapsules. Multivalent interactions of complementary ligands on the nanoparticle surface provide stability to these capsules. Unlike covalently cross-linked microcapsules, the reversible nature of these bridging interactions can be used to manipulate the size of these capsules via introduction of competing adamantane containing amphiphilic guest molecules. Partial disruption of interfacial cross-linking allows microcapsules to coalesce with each other to form larger …

An anticancer drug (5-fluorouracil) was conjugated to the surface of gold nanoparticles through a photocleavable o-nitrobenzyl linkage. In this system, the particle serves as both cage and carrier for the therapeutic, providing a nontoxic conjugate that effectively releases the payload upon long wavelength UV irradiation.

Formation Of Ordered Cellular Structures In Suspension Via Label-Free Negative Magnetophoresis, Md Krebs, Rm Erb, Bb Yellen, B Samanta, A Bajaj, Vm Rotello, E Alsberg
Vincent Rotello
The creation of ordered cellular structures is important for tissue engineering research. Here, we present a novel strategy for the assembly of cells into linear arrangements by negative magnetophoresis using inert, cytocompatible magnetic nanoparticles. In this approach, magnetic nanoparticles dictate the cellular assembly without relying on cell binding or uptake. The linear cell structures are stable and can be further cultured without the magnetic field or nanoparticles, making this an attractive tool for tissue engineering.

Gold nanoparticles functionalized with water-soluble zwitterionic ligands form kinetically stable complexes with hydrophobic drugs and dyes. These drugs and dyes are efficiently released into cells, as demonstrated through fluorescence microscopy and cytotoxicity assays. Significantly, there is little or no cellular uptake of particle, making these low toxicity particles promising for delivery applications.

Surface-bound biomolecular fragments enable “smart” materials to recognize cells and other particles in applications ranging from tissue engineering and medical diagnostics to colloidal and nanoparticle assembly. Such smart surfaces are, however, limited in their design to biomolecular selectivity. This feature article demonstrates, using a completely nonbiological model system, how specificity can be achieved for particle (and cell) binding, employing surface designs where immobilized nanoscale adhesion elements are entirely nonselective. Fundamental principles are illustrated by a model experimental system where 11 nm cationic nanoparticles on a planar negative silica surface interact with flowing negative silica microspheres having 1.0 and 0.5 μm …

Controlled self-assembly of fluorinated FePt nanoparticles from different solvent mixtures has been used to create superhydrophobic surfaces with varying topology and stickiness towards water. The ability to tune surface stickiness provides a means for fluid handling, as demonstrated by surface-to-surface transfer of water droplets.

Eleven cationic, monolayer-protected quaternary ammonium-functionalized gold nanoparticles (ANPs) were prepared and investigated for their ability to quench the fluorescence of a poly(p-phenyleneethynylene) (PPE) that features carboxylate groups to enable electrostatic interactions with the ANPs. Depending upon their structures, the ANPs displayed binding constants to the PPE from 8 × 107 to 1010 M−1, with particularly high affinity observed with aromatic functionalized ANPs capable of aromatic stacking. These binding constants were obtained by analyzing the quenching data using a modified Stern–Volmer formalism.

Aggregation in nondiffusion limited colloidal particle suspensions follows a temporal power-law dependence that is consistent with classical diffusion limited cluster aggregation models; however, the dynamic scaling exponents observed in these systems are not adequately described by diffusion limited cluster aggregation models, which expect these scaling exponents to be constant over all experimental conditions. We show here that the dynamic scaling exponents for 10 μm particles increase with the particle concentration and the particle-particle free energy of interaction. We provide a semiquantitative explanation for the scaling behavior in terms of the long-ranged particle-particle interaction potential.

Accessibility Of Cylindrical Channels Within Patterned Mesoporous Silica Films Using Nanoparticle Diffusion, Ht Chen, Ta Crosby, Mh Park, S Nagarajan, Vm Rotello, Jj Watkins
Vincent Rotello
Mesoporous silica films with well ordered nanochannels (approximately 7 nm in diameter) oriented parallel to the substrate were synthesized using supercritical carbon dioxide mediated silica deposition within templates comprised of triblock copolymers blended with strongly associating homopolymers. The films were patterned at the device level by conventional lithography and etched to yield periodic circular features approximately 20 µm in diameter. The nanoscale channels remained accessible to penetrant diffusion as shown by dye uptake experiments. The nanochannel arrays were used as miniature size exclusion columns to mediate nanoparticle diffusion.

The cross section for photoproduction of pion pairs from hydrogen has been calculated from the cut-off static theory, assuming the energy is sufficiently low that one of the mesons is produced in an S state, the other in a P state. It is shown that the cross section for this process can be expressed exactly in terms of the P-wave scattering phase shifts, provided the S-wave meson-nucleon interactions and the meson-meson interaction can be neglected. The theoretical predictions obtained here are in general agreement with preliminary experimental results.

The neutron elastic magnetic form factor GMn has been extracted from quasielastic electron scattering data on deuterium with the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. The kinematic coverage of the measurement is continuous from Q2=1 GeV2 to 4.8 GeV2. High precision was achieved by employing a ratio technique in which many uncertainties cancel, and by a simultaneous in-situ calibration of the neutron detection efficiency, the largest correction to the data.

Semi-inclusive π+ [pi superscript +] electroproduction on protons has been measured with the CLAS detector at Jefferson Lab. The measurement was performed on a liquid-hydrogen target using a 5.75 GeV electron beam. The complete five-fold differential cross sections were measured over a wide kinematic range including the complete range of azimuthal angles between hadronic and leptonic planes, ϕ [phi], enabling us to separate the ϕ-dependent [phi-dependent] terms. Our measurements of the ϕ-independent [phi-independent] term of the cross section at low Bjorken x were found to be in fairly good agreement with pQCD calculations. Indeed, the conventional current fragmentation calculation can …

We report on the results of the first measurement of exclusive f_{0}(980) meson photoproduction on protons for E_{gamma}=3.0-3.8 GeV and -t=0.4-1.0 GeV2. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The resonance was detected via its decay in the pi;{+}pi;{-} channel by performing a partial wave analysis of the reaction gammap-->ppi;{+}pi;{-}. Clear evidence of the f_{0}(980) meson was found in the interference between P and S waves at M_{pi;{+}pi;{-}} approximately 1 GeV. The S-wave differential cross section integrated in the mass range of the f_{0}(980) was found to be a factor of about …

A search for exotic mesons in the pi;{+}pi;{+}pi;{-} system photoproduced by the charge exchange reaction gammap-->pi;{+}pi;{+}pi;{-}(n) was carried out by the CLAS Collaboration at Jefferson Lab. A tagged-photon beam with energies in the 4.8 to 5.4 GeV range, produced through bremsstrahlung from a 5.744 GeV electron beam, was incident on a liquid-hydrogen target. A partial wave analysis was performed on a sample of 83 000 events, the highest such statistics to date in this reaction at these energies. The main objective of this study was to look for the photoproduction of an exotic J;{PC}=1;{-+} resonant state in the 1 …
