Viruses as self-assembled nanocontainers for encapsulation of functional cargoes

چکیده
−Viruses naturally exhibit an incredible variety of sophisticated nanostructures, which makes them ideal biological building blocks for nanoengineered material research. By mimicking their spontaneous assembly process, tremendous advances have been made towards utilizing virus and virus-like particles (VLPs) as protein cages, scaffolds, and templates for nanomaterials in the last few years. This review outlines recent progress in the field of bionanotechnology in which viruses are introduced to encapsulate various functional cargoes in a precise and controlled fashion. The encapsulation mechanisms are summarized into three main strategies: electrostatic interaction, chemical conjugation, and covalent attachment by genetic manipulation. The combination with chemical modification and genetic engineering heralds a brilliant future for fabrication of functional nanomaterials. These well-defined architectures will find attractive applications in biosensing, drug delivery, enzyme confinement, light-harvesting system, and pharmaceutical therapy.

متن کاملSequence-selective encapsulation and protection of long peptides by a self-assembled FeII8L6 cubic cage
Self-assembly offers a general strategy for the preparation of large, hollow high-symmetry structures. Although biological capsules, such as virus capsids, are capable of selectively recognizing complex cargoes, synthetic encapsulants have lacked the capability to specifically bind large and complex biomolecules. Here we describe a cubic host obtained from the self-assembly of FeII and a zinc-p...
