DNA sequences designed to either stimulate a specific immune response or to down-regulate an undesirable response deliver superior performance when organized on nanoparticles to reach their intended cellular targets.
Gold nanotubes engineered to a specified length, modified surfaces, and to have other desirable characteristics showed expected abilities to enter tumor cells in laboratory studies, and to distribute to tissues within live mice as intended.
Positioning two or more molecules along a long DNA strand can cause the DNA molecule to adopt different shapes if the molecules interact. Quickly and cheaply separating these shapes by a simple gel electrophoresis assay provides a wealth of information about how the molecules interact.
Design and computational simulation of amyloid proteins of diverse functions from diverse sources enable the self-assembly of proteins that could provide scaffolds for diverse applications.
Iterative coupling, purification, and cyclization of a large collection of organic building blocks promises a vast array of complex small and medium sized molecules as candidates for drug discovery, catalysis, and nanotechnology.
In tests in a mouse model of advanced atherosclerosis, core-shell nanoparticles, composed of block copolymers and targeted to sites of inflammation and vascular injury, delivered a bioactive peptide that improved key properties of advanced plaques.
Mixing two different types of cylindrical nanoparticles causes them to reorganize into smaller spherical nanoparticles. A mechanism to release drugs only inside cells that internalize both types?
A simple method of producing nanoporous alumina surface discourages bacteria from attaching and forming biofilms, with potential applications in medicine, dentistry, and food processing.
Scaffolded DNA origami is combined with hinges of single- or double-stranded DNA to built simple machines parts that have been combined to program simple to complex motions.
Combinations of different types of DNA nanorobots, implementing different logic gates, work together to tag a specific type of cell in a living cockroach depending on the presence or absence of two protein signals.
New software makes it possible to generate 3D structures of proteins without artificially incorporating metal atoms in the proteins, making it possible to study many molecular machines using data that could not previously be analyzed.
A more general computational framework predicts the structures of 2D and 3D-curved DNA nanostructures impossible to predict using previously available computational methods. May lead to 3D-printing DNA nanostructures?
Design principles have been developed and tested to construct novel synthetic protein monomers that can self-assemble into large, open protein cages for potential use in vaccines and drug delivery.
A nanoparticle that self-assembles from porphyrin, cholic acid, amino acids, and polyethylene glycol is a promising vehicle for delivering both imaging agents and cancer drugs to tumors.
Nicholas Negroponte, founder of the MIT media lab and the One Laptop Per Child program, gave a TED talk in March 2014 titled A 30-Year History of the Future. Click to access the talk or the TEDBlog article discussing the talk. Negroponte highlights some cutting-edge technological developments of the past that had been openly scorned [...]
Foresight friends can use this discount to attend the SENS Rejuvenation Biotechnology Conference August 21-23, 2014 Santa Clara, California.
Enveloped DNA nanostructures were developed to escape attacks from nucleases and the immune system, opening a path to ever more sophisticated DNA nanomedical devices.
The photos from the 2014 Foresight Technical Conference highlight entrepreneurial efforts in space, biotechnology, and life extension.
The complex molecular recognition code of RNA offers RNA nanotechnology a greater variety of 3D structures and functions than are present in DNA nanotechnology, but the RNA structures can be fragile. New RNA triangles that resist boiling solve this problem.
