Biophysical restriction of growth area using a monodispersed gold sphere nanobarrier prolongs the mitotic phase in HeLa cells

Abstract

Homogeneous 83 nm gold nanospheres with a human fibronectin-coated substrate surrounding the cells induce biophysical cues which result in a delay in the mitotic phase of the cell cycle.

Probing Inherent Optical Anisotropy in Substrates via Direct Nanoimaging of Mie Scattering

“…Therefore, this study proposes that the electric field distribution induced by Mie scattering can be utilized to study optical material properties. Through a combination of experimental observations and FDTD simulations, we elucidated the details of the satellite-like structures induced by Mie scattering from superspherical gold nanoparticles (s-AuNPs) as a Mie probe on the substrates. By comparing the behavior of Mie scattering on ReS 2 , which is known for its optical anisotropy, − with that of molybdenum disulfide (MoS 2 ), a substrate lacking such anisotropy, we were able to probe and visualize the Mie scattering patterns.…”
