Enzyme Nanorings

Tsui-Fen Chou†, Christopher So§, Brian R. White†, Jonathan C. T. Carlson†, Mehmet Sarikaya§ and Carston R. Wagner†‡*

We have demonstrated that nanostructures, and in particular nanorings incorporating a homodimeric enzyme, can be prepared by chemically induced self-assembly of dihydrofolate reductase (DHFR)-histidine triad nucleotide binding 1 (Hint1) fusion proteins. The dimensions of the nanorings were found by static light scattering and atomic force microscopy studies to be dependent on the length and composition of the peptide linking the fusion proteins, ranging in size from 10 to 70 nm in diameter and 64 to 740 kDa. The catalytic efficiency of the nanorings was found to be dependent on ring size, thus suggesting that the arrangement of supermolecular assemblies of enzymes may be used to control their catalytic parameters.

Assembly and Functionalization of DNA−Polymer Microcapsules

Francesca Cavalieri†‡, Almar Postma†, Lillian Lee†and Frank Caruso†*

We report the synthesis and characterization of DNA-grafted poly(N-isopropylacrylamide) (PNIPAM) micelles, their assembly into multilayered thin films, and the subsequent generation and poly(ethylene glycol) (PEG) functionalization of DNA−PNIPAM microcapsules. Multilayer films were assembled by sequentially depositing DNA-grafted PNIPAM micelles containing the cDNA sequences polyA₃₀ or polyT₃₀ (i.e., PNIPAM-A₃₀ or PNIPAM-T₃₀). DNA−polymer microcapsules were obtained by the alternate deposition of PNIPAM-A₃₀ and PNIPAM-T₃₀ onto silica particles, followed by removal of the template core. Upon removal of the silica core particle, shrinkage of between 30 and 50% was observed for the microcapsules. The presence of PNIPAM within the DNA−polymer hybrid film reduces the permeability of the microcapsules to macrosolutes (e.g., dextran) compared with microcapsules made solely of DNA. The hydrophobic core of the DNA-grafted PNIPAM micelles was designed to contain alkyne “click” groups, which were exploited to covalently couple azide-bearing low-fouling PEG to the DNA−PNIPAM microcapsules. The combination of hydrophobic and reactive “click” nanodomains, along with the degradability of DNA, offers a multifunctional and versatile DNA−polymer capsule system that is envisioned to find applications in the controlled delivery of therapeutics.

Impact of Nanotechnology on Drug Delivery

Nanotechnology is the engineering and manufacturing of materials at the atomic and molecular scale. In its strictest definition from the National Nanotechnology Initiative, nanotechnology refers to structures roughly in the 1−100 nm size regime in at least one dimension. Despite this size restriction, nanotechnology commonly refers to structures that are up to several hundred nanometers in size and that are developed by top-down or bottom-up engineering of individual components. Herein, we focus on the application of nanotechnology to drug delivery and highlight several areas of opportunity where current and emerging nanotechnologies could enable entirely novel classes of therapeutics.

Physical approaches to biomaterial design

Samir Mitragotri¹ & Joerg Lahann²

The development of biomaterials for drug delivery, tissue engineering and medical diagnostics has traditionally been based on new chemistries. However, there is growing recognition that the physical as well as the chemical properties of materials can regulate biological responses. Here, we review this transition with regard to selected physical properties including size, shape, mechanical properties, surface texture and compartmentalization. In each case, we present examples demonstrating the significance of these properties in biology. We also discuss synthesis methods and biological applications for designer biomaterials, which offer unique physical properties.

Cancer vaccines developed so far typically rely on cell manipulation techniques in the laboratory followed by re-introduction of the cells into the patient. Now, a polymeric material is shown to program and control the trafficking of immune cellsin situ, resulting in specific and protective anti-tumour properties.

Polymer chain dynamics and glass transition in athermal polymer/nanoparticle mixtures

Hyunjoon Oh & Peter F. Green

doi:10.1038/nmat2354

Tailoring the properties of polymer nanocomposites—polymers incorporating nanoparticles—is essential to develop biomedical, or even electronic, applications. It is now shown that accurate control of the nanoparticle concentration in nanocomposites prepared from athermal mixtures considerably varies the physical properties with respect to the host polymer.
