Efficient Gene Delivery Vectors By Tuning The Surface Charge Density Of Amino Acid-Functionalized Gold Nanoparticles, Ps Ghosh, Ck Kim, G Han, Ns Forbes, Vm Rotello

Vincent Rotello

Gold colloids functionalized with amino acids provide a scaffold for effective DNA binding with subsequent condensation. Particles with lysine and lysine dendron functionality formed particularly compact complexes and provided highly efficient gene delivery without any observed cytotoxicity. Nanoparticles functionalized with first generation lysine dendrons (NP-LysG1) were approximately 28-fold superior to polylysine in reporter gene expression. These amino acid-based nanoparticles were responsive to intracellular glutathione levels, providing a tool for controlled release and concomitant expression of DNA.

Comparative Genomics Of Geobacter Chemotaxis Genes Reveals Diverse Signaling Function, Hoa T. Tran, Julia Krushkal, Frances M. Antommattei, Derek R. Lovley, Robert Weis

Robert Weis

Background Geobacter species are δ-Proteobacteria and are often the predominant species in a variety of sedimentary environments where Fe(III) reduction is important. Their ability to remediate contaminated environments and produce electricity makes them attractive for further study. Cell motility, biofilm formation, and type IV pili all appear important for the growth of Geobacter in changing environments and for electricity production. Recent studies in other bacteria have demonstrated that signaling pathways homologous to the paradigm established for Escherichia coli chemotaxis can regulate type IV pili-dependent motility, the synthesis of flagella and type IV pili, the production of extracellular matrix material, and …

Multiplexed Screening Of Cellular Uptake Of Gold Nanoparticles Using Laser Desorption/Ionization Mass Spectrometry, Zj Zhu, Ps Ghosh, Or Miranda, Rw Vachet, Vm Rotello

Vincent Rotello

Gold nanoparticles (AuNPs) are highly promising candidates as drug delivery agents into cells of interest. We describe for the first time the multiplexed analysis of nanoparticle uptake by cells using mass spectrometry. We demonstrate that the cellular uptake of functionalized gold nanoparticles with cationic or neutral surface ligands can be readily determined using laser desorption/ionization mass spectrometry of cell lysates. The surface ligands have “mass barcodes” that allow different nanoparticles to be simultaneously identified and quantified at levels as low as 30 pmol. Using this method, we find that subtle changes to AuNP surface functionalities can lead to measurable changes …

Self-Assembly And Cross-Linking Of Fept Nanoparticles At Planar And Colloidal Liquid-Liquid Interfaces, P Arumugam, D Patra, B Samanta, Ss Agasti, C Subramani, Vm Rotello

Vincent Rotello

Terpyridine thiol functionalized FePt and Au NPs were self-assembled and cross-linked at the liquid−liquid interfaces using Fe(II) metal ion. Complexation of terpyridine with Fe(II) metal ion leads to NP network and affords stable membranes and colloidal shells at the liquid−liquid interfaces.

Manipulating Microparticles With Single Surface-Immobilized Nanoparticles, J Zhang, S Srivastava, R Duffadar, Jm Davis, Vm Rotello, Mm Santore

Vincent Rotello

This experimental study explores the capture and manipulation of micrometer-scale particles by single surface-immobilized nanoparticles. The nanoparticles, approximately 10 nm in diameter, are cationic and therefore attract the micrometer-scale silica particles in an analyte suspension. The supporting surface on which the nanoparticles reside is negative (also silica) and repulsive toward approaching microparticles. In the limit where there are as few as 9 nanoparticles per square micrometer of collector, it becomes possible to capture and hold micrometer-scale silica particles with single nanoparticles. The strong nanoparticle−microparticle attractions, their nanometer-scale protrusion forward of the supporting surface, and their controlled density on the supporting …

Tuneable Pseudorotaxane Formation Between A Biotin-Avidin Bioconjugate And Cbpqt(4+), St Caldwell, G Cooke, A Cooper, M Nutley, G Rabani, V Rotello, Bo Smith, P Woisel

Vincent Rotello

A biotinylated 1,5-dialkoxynaphthalene derivative has been shown to have the ability to bind strongly to avidin and thus act as an artificial binding site for cyclobis(paraquat-p-phenylene) thereby facilitating the formation of a tuneable pseudorotaxane-based bioconjugate.

Electricity Generation By Geobacter Sulfurreducens Attached To Gold Electrodes, H Richter, K Mccarthy, Kp Nevin, Jp Johnson, Vm Rotello, Dr Lovley

Vincent Rotello

The versatility of gold for electrode manufacture suggests that it could be an ideal material for some microbial fuel cell applications. However, previous studies have suggested that microorganisms that readily transfer electrons to graphite do not transfer electrons to gold. Investigations with Geobacter sulfurreducens demonstrated that it could grow on gold anodes producing current nearly as effectively as with graphite anodes. Current production was associated with the development of G. sulfurreducens biofilms up to 40 μm thick. No current was produced if pilA, the gene for the structural protein of the conductive pili of G. sulfurreducens, was deleted. The finding …

Controlled Nanoparticle Assembly Through Protein Conformational Changes, H Bayraktar, S Srivastava, Cc You, Vm Rotello, Mj Knapp

Vincent Rotello

Selective surface recognition by proteins provides programmed bottom-up assembly of synthetic nanomaterials. We have investigated the controlled self-assembly of functionalized gold nanoparticles (Au-TAsp) with cytochrome c (Cyt c) and apoCyt c through complementary electrostatic interactions. Au-TAsp formed discrete, water-soluble adducts with native Cyt c, whereas unfolded apoCyt c induced nanocomposite formation at high Cyt c : Au-TAsp ratios. The binding of random-coil apoCyt c to Au-TAsp at low ratios induced α-helix formation in soluble nanocomposites, but at elevated ratios insoluble micron-scale aggregates were formed. The local structure of the assemblies was critically dependent on the Cyt c : Au-TAsp ratio. …

Inspiration (And Perspiration) From Biology, Vm Rotello

Vincent Rotello

The exquisite structures produced by biological systems provide inspiration for the fabrication of nanomaterials. We sometimes forget, however, that Nature can provide muscle while serving as a Muse--a wide array of nanosystems are produced biologically that can be used for the design of functional materials. At the 2007 Materials Research Society Fall Meeting in Boston, Symposium MM (Biomolecular and Biologically Inspired Interfaces and Assemblies) highlighted the synergy between researchers using biomaterials and those using nature as a model for synthetic and quasi-synthetic systems. The symposium was organized by Vincent Rotello, Paula Hammond, Molly Stevens, Jeffrey Tok, and Darrin Pochan, with …
