Integrated Magnetic Bionanocomposites Through Nanoparticle-Mediated Assembly Of Ferritin, S Srivastava, B Samanta, Bj Jordan, R Hong, Q Xiao, Mt Tuominen, Vm Rotello Sep 2007

Integrated Magnetic Bionanocomposites Through Nanoparticle-Mediated Assembly Of Ferritin, S Srivastava, B Samanta, Bj Jordan, R Hong, Q Xiao, Mt Tuominen, Vm Rotello

Vincent Rotello

Magnetic (FePt) and nonmagnetic (Au) nanoparticles were used to assemble ferritin into near-monodisperse bionanocomposites featuring regular interparticle spacing. The FePt/ferritin assemblies are integrated magnetic materials with ferritin providing added magnetic volume fraction to the magnetic nanocomposite. These assemblies differ from either of their constituent particles in terms of blocking temperature (TB), net magnetic moment, coercivity, and remnance.

Biomimetic Interactions Of Proteins With Functionalized Nanoparticies: A Thermodynamic Study, M De, Cc You, S Srivastava, Vm Rotello

Vincent Rotello

Gold nanoparticles (NPs) functionalized with L-amino acid-terminated monolayers provide an effective platform for the recognition of protein surfaces. Isothermal titration calorimetry (ITC) was used to quantify the binding thermodynamics of these functional NPs with alpha-chymotrypsin (ChT), histone, and cytochrome c (CytC). The enthalpy and entropy changes for the complex formation depend upon the nanoparticle structure and the surface characteristics of the proteins, e.g., distributions of charged and hydrophobic residues on the surface. Enthalpy-entropy compensation studies on these NP-protein systems indicate an excellent linear correlation between DeltaH and TDeltaS with a slope (alpha) of 1.07 and an intercept (TDeltaS0) of 35.2 …

A sensor array comprising six functionalized poly(p-phenyleneethynylene) polymers was constructed and used to detect and identify protein analytes. The presence of proteins alters the fluorescence properties of the polymers, generating a distinct fluorescence response pattern for a given protein. Linear discriminant analyses accurately differentiate the patterns of 17 proteins at nano- to micromolar concentrations. An identification accuracy of 97% was obtained on the basis of the tests with 68 unknown protein samples from the training set.

Trimethylammonium functionalized gold nanoparticles are demonstrated as templates for the assembly of peptide fragments and their subsequently promoted ligation. This system displays the use of organically tailored nanoparticles as effective supramolecular reagents for catalyzing bond-forming reactions and may also serve as a model for prebiotic conditions where charged surfaces may have promoted the polymerization of the early biopolymers.

Core-Like Particles Of An Enveloped Animal Virus Can Self-Assemble Efficiently On Artificial Templates, Nl Goicochea, M De, Vm Rotello, S Mukhopadhyay, B Dragnea

Vincent Rotello

Alphaviruses are animal viruses holding great promise for biomedical applications as drug delivery vectors, functional imaging probes, and nanoparticle delivery vesicles because of their efficient in vitro self-assembly properties. However, due to their complex structure, with a protein capsid encapsulating the genome and an outer membrane composed of lipids and glycoproteins, the in-vitro self-assembly of virus-like particles, which have the functional virus coat but carry an artificial cargo, can be challenging. Fabrication of such alphavirus-like particles is likely to require a two-step process: first, the assembly of a capsid structure around an artificial core, second the addition of the membrane …

New measurements of the spin structure functions of the proton and deuteron g1p(x,Q2) and g1d(x,Q2) in the nucleon resonance region are compared with extrapolations of target-mass-corrected next-to-leading-order (NLO) QCD fits to higher energy data. Averaged over the entire resonance region (W<2 >GeV), the data and QCD fits are in good agreement in both magnitude and Q2 dependence for Q2>1.7 GeV2/c2. This “global” duality appears to result from cancellations among the prominent “local” resonance regions: in particular strong σ3/2 contributions in the Δ(1232) region appear to be compensated by strong σ1/2 contributions in the resonance region centered on 1.5 GeV. …

The photoproduction of vector mesons on various nuclei has been studied using the CLAS detector at Jefferson Laboratory. The vector mesons, rho, omega, and varphi, are observed via their decay to e;{+}e;{-}, in order to reduce the effects of final-state interactions in the nucleus. Of particular interest are possible in-medium effects on the properties of the rho meson. The rho mass spectrum is extracted from the data on various nuclei, 2H, C, Fe, and Ti. We observe no significant mass shift and some broadening consistent with expected collisional broadening for the rho meson.

Differential cross sections for the reaction γp→K*0Σ+ are presented in the photon energy range of 1.7 to 3.0 GeV. The K*0 was detected by its decay products, K+π-, in the Continuous Electron Beam Accelerator Facility's large acceptance spectrometer (CLAS) detector at the Thomas Jefferson National Accelerator Facility. These data are the first K*0 photoproduction cross sections ever published over a broad range of angles. Comparison with a theoretical model based on the vector and tensor K*-quark couplings shows good agreement with the data, except at forward angles, suggesting that the role of scalar κ meson exchange should be investigated.

Differential cross sections for the reaction $\gamma p \to p \pi^0$ have been measured with the CEBAF Large Acceptance Spectrometer (CLAS) and a tagged photon beam with energies from 0.675 to 2.875 GeV. The results reported here possess greater accuracy in the absolute normalization than previous measurements. They disagree with recent CB-ELSA measurements for the process at forward scattering angles. Agreement with the SAID and MAID fits is found below 1 GeV. The present set of cross sections has been incorporated into the SAID database, and exploratory fits have been extended to 3 GeV. Resonance couplings have been extracted and …

The cross section and decay angular distributions for the coherent ϕ-meson photoproduction on the deuteron have been measured for the first time up to a squared four-momentum transfer t=(pγ-pϕ)2=-2 GeV2/c2, using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The cross sections are compared with predictions from a rescattering model. In a framework of vector meson dominance, the data are consistent with the total ϕ-N cross section σϕN at about 10 mb. If vector meson dominance is violated, a larger σϕN is possible by introducing a larger t slope for the ϕN→ϕN process than that for the γN→ϕN …

Photoproduction of the cascade resonances has been investigated in the reactions γp→K+K+(X) and γp→K+K+π-(X). The mass splitting of the ground state (Ξ-,Ξ0) doublet is measured to be 5.4±1.8 MeV/c2, consistent with existing measurements. The differential (total) cross sections for the Ξ- have been determined for photon beam energies from 2.75 to 3.85 (4.75) GeV and are consistent with a production mechanism of Y*→K+Ξ- through a t-channel process. The reaction γp→K+K+π-[Ξ0] has also been investigated to search of excited cascade resonances. No significant signal of excited cascade states other than the Ξ-(1530) is observed. The cross-section results of the Ξ-(1530) have …

The photoproduction of vector mesons on various nuclei has been studied using the CLAS detector at Jefferson Laboratory. The vector mesons, rho, omega, and varphi, are observed via their decay to e;{+}e;{-}, in order to reduce the effects of final-state interactions in the nucleus. Of particular interest are possible in-medium effects on the properties of the rho meson. The rho mass spectrum is extracted from the data on various nuclei, 2H, C, Fe, and Ti. We observe no significant mass shift and some broadening consistent with expected collisional broadening for the rho meson.
