Innovative technology for biological nanoparticles enables combined treatment against cancerous tumors

Researchers from Tel Aviv University have developed an innovative platform based on nanoparticles, which enables the precise transport of two drugs at the same time to cancerous tumor sites, while improving treatment efficiency and reducing toxicity to healthy cells.
When a point electromagnetic source that propagates perfect circular wavefronts (bottom row, left) is placed in front of a rigid dielectric surface, significant reflections and distortions in the wavefronts are observed (bottom row, right). When the same surface is coated with metal formations designed in the article according to the Generalized Huygens' Condition, the disturbances disappear thanks to the general-angular irregularities (bottom row, middle) and the ideal propagation is fully restored (as if the waves were propagating in free space, similar to the scenario on the left). Top row: Left: the measurement setup in which the surface (device) is illuminated and the field transmitted by a detector (detector) is measured. Middle: the dielectric surface that is created with a coating to suppress reflections at all angles. Right: reference surface without the coating (for which a significant return was observed).
