Penn team uses self-assembly to make molecule-sized particles with patches of charge


Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small ...


University of Pennsylvania Researchers Demonstrate a Flexible, One-Step Assembly of Nanoscale Structures


Scientists at the University of Pennsylvania have created a one-step, repeatable method for the production of functional nanoscale patterns or motifs with adjustable features, size and shape using a single master "plate." Researchers took advantage of the elastic instability of a widely used, ...


Surface dislocation nucleation: Strength is but skin deep at the nanoscale, Penn engineers discover


For centuries, engineers have bent and torn metals to test their strength and ductility. Now, materials scientists at the University of Pennsylvania School of Engineering and Applied Science are studying the same metals but at nanoscale sizes in the form of wires a thousand times thinner than a ...


Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current


University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. Researchers developed this tiny carbon-based tool to probe cells with minimal intrusion and inject ...


Researchers at University of Pennsylvania develop method for mass production of nanogap electrodes


Researchers at the University of Pennsylvania have developed a reliable, reproducible method for parallel fabrication of multiple nanogap electrodes, a development crucial to the creation of mass-produced nanoscale electronics. Charlie Johnson, associate professor in the Department of Physics ...


Sand, Other Granular Matter's Behavior Is Better Defined

Penn Physicists Develop Force Law for Granular Impacts


A single grain of sand is tiny, but solid, and shares the physical properties of other solid matter. But pack or transport millions of grains together - as modern society does with coffee grounds, flour and industrial chemicals - and granular materials act differently, baffling engineers. They ...


Magnetic field points the way for metallic nanorods with hydrogen peroxide propulsion

Remote Control Nanomotor


Like their normally sized analogues, nanoscale machines and robots need motors to function. Some time ago, a team at Pennsylvania State University developed a clever engine to "drive" nanoscopic metal rods; however, until now, these tiny "submarines" roamed at random through the solution. Now ...
