A computer-generated hologram projects a beam of light that focuses to interlocking inclined rings, a simple knot known as a Hopf link. Each ring acts as an optical trap that can gather and hold micrometer-scale objects. The same hologram also imposes phase gradients around the Hopf link, thereby creating a knot in the total optical force field.

Join Materials Scientists from NYU who will talk about their own work engineering materials that shape our future!

Cornstarch suspension is a common kitchen “fluid.” It was suggested to be used in protecting armors since it becomes hard when under stress (force). The current work shows that the particulate suspension may act like a “fluid chisel” since an external force will be focused onto a receiving substrate (for example the wall of the fluid container).

A Whispering gallery mode carousel is a photonic mechanism for enhanced nanoparticle detection in biosensing.


Investigators at the New York University MRSEC and the University of Minnesota MRSEC have reported the growth of glycine nanocrystals inside aligned cylindrical nanopores of a polymer monolith that was derived from an ordered block polymer precursor.

Dense particle packings have served as useful models of the structures of liquid, glassy and crystalline states of matter, granular media, and biological systems.

Discover magazine named a finding by NYU MRSEC investigators Jasna Brujic, Maxime Clusel, Eric Corwin, and Alexander Siemens one of the top 100 stories of 2009

Professor Ned Seeman has been awarded the Kavli Prize in Nanoscience. The prize is designed to recognize outstanding scientific research, honor highly creative scientists, promote public understanding of scientists and their work, and to foster international cooperation among scientists.

New insight into disordered structures that result when tetrahedra particles are poured into a (large) container are discovered.
