PATHOGENESIS AND SYMMETRY. "Broken symmetry, at the nano level, of biomolecules, is key to phage invasion of a host cell, and take-over of the cell’s RNA-DNA replication processes." https://lnkd.in/dtkZvcG View in LinkedIn

ANISOTROPIC DNA NANOPARTICLES. "Anisotropic nanoparticles can provide considerable opportunities for assembly of nanomaterials with unique structures and properties." https://lnkd.in/d89Jbyi View in LinkedIn

COUPLINGS. "The polarization of light can be rotated in materials with an absence of molecular or structural mirror symmetry. While this rotating ability is normally rather weak in naturally occurring chiral materials, artificial chiral metamaterials have demonstrated extraordinary rotational ability by engineering intra-molecular couplings." https://lnkd.in/dScRSz9 View in LinkedIn

UNUSUAL PROPERTIES. "Negative index metamaterials (NIMs) give rise to many unusual properties and phenomena, which may lead to important applications such as a superlens, subwavelength cavity and slow light devices." https://lnkd.in/dB36GiY View in LinkedIn

NEGATIVELY REFRACTIVE CHIRAL METAMATERIALS. "Chirality extends the class of negatively refracting metamaterials by endowing a richer palette of electromagnetic properties. Millions of research dollars have been spent during the last decade on this topic, following experimental reports of negative refraction in certain metamaterials under microwave illumination...negative refraction is not exclusive to artificial metamaterials: certain biological structures and naturally occurring minerals also exhibit negative refraction." https://lnkd.in/dZSW9Fz View in LinkedIn

BRILLIANT WORK on metamaterials driven by profound mathematical insights into the physical properties of materials. A lovely read. https://www.osapublishing.org/oe/fulltext.cfm?uri=oe-18-14-14553&id=202793 View in LinkedIn

PREDICTION. "Recently, it was predicted that strong enough optical activity may result in negative refraction and negative reflection." https://www.osapublishing.org/viewmedia.cfm?uri=oe-18-14-14553&seq=0 View in LinkedIn

"CHIRAL METAMATERIALS (CMMs), which are artificial materials that lack any planes of mirror symmetry, possess strong ability to rotate the plane of polarization of electromagnetic waves. This ability is called optical activity which is of great interest to many areas of science, for example, analytical chemistry and molecular biology." https://www.osapublishing.org/viewmedia.cfm?uri=oe-18-14-14553&seq=0 View in LinkedIn

SUPRAMOLECULAR CHIRALITY. "Since the steroidal molecules are highly asymmetric, the resulting hierarchical assembles may have the corresponding three-dimensional structure with supramolecular chirality. Starting from molecular chirality, each assembly must be chiral." https://lnkd.in/dR7Kdj8 View in LinkedIn
