Antimicrobial Targets

Research team from University of Houston find that the light-activated gold nanoparticles destroy potentially deadly bacterial cells in seconds

North Carolina State University researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ideas for better, greener and safer nanotechnology and could lead to enhanced efficiency of antimicrobial products used in agriculture and personal care.

There’s an urgent demand for new antimicrobial compounds that are effective against constantly emerging drug-resistant bacteria. Two robotic chemical-synthesizing machines, named Symphony X and Overture, have joined the search. Their specialty is creating custom nanoscale structures that mimic nature’s proven designs. They’re also fast, able to assemble dozens of compounds at a time.

Does the widespread and still proliferating use of antimicrobial household products cause more harm than good to consumers and the environment? Evidence compiled in a new feature article published in the journal Environmental Science & Technology (ES&T) by Arizona State University professor Rolf Halden shows that decades of widespread use of antimicrobials has left consumers with no measurable benefits.
