Protocol for detecting substrates in living cells by targeted molecular probes through hyperpolarized 129Xe MRI

STAR Protocols, 2022
Summary: Due to limited detection sensitivity and contrast limitation, imaging substrates with 129Xe MRI in living cells is still a challenge. Here, we present an effective protocol to detect and image substrates in human lung cancer cells A549 with ...

Dynamical scattering models in optomechanics: going beyond the ‘coupled cavities’ model

New Journal of Physics, 2012
Recently we calculated the radiation field and the optical forces acting on a moving object inside a general one-dimensional configuration of immobile optical elements (Xuereb et al 2010 Phys. Rev. Lett. 105 013602).

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
