POSA for fast, amplified and multiplexed protein imaging

open access: yesNature Communications
Fluorescent π-conjugated polymers (FCPs) are known for their superior brightness but are still unavailable for highly multiplexed molecular imaging in single cells as they are hydrophobic and lack targeting capability toward biomolecules.

Signal regeneration techniques for advanced modulation formats

open access: yes
We review recent results on all-optical regeneration of phase encoded signals based on phase sensitive amplification achieved by avoiding phase-to-amplitude conversion in order to facilitate the regeneration of amplitude/phase encoded (QAM ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

SURVEY OF HYBRID EDFA/RAMAN IN C AND L BANDS

open access: yesRevista Ingeniería, Matemáticas y Ciencias de la Información, 2017
Optical amplifiers have had a breakthrough in recent years. Initially, amplification of optical signals was performed passing the optical signal to the electrical domain, then the amplified signal back again to the optical domain.

Pulse characteristics of silicon double barrier optical sensors with signal amplification [PDF]

open access: yes, 2008
The pulse characteristics of optical sensors with double potential barriers formed on the opposite sides of a high-resistivity (v) silicon substrate have been studied. The first barrier is formed by multiple micro-sized Ti–vSi contact barriers surrounded

Field-trial of an all-optical PSK regenerator/multicaster in a 40 Gbit/s, 38 channel DWDM transmission experiment [PDF]

open access: yes, 2012
The performance of future ultra-long haul communication systems exploiting phase-encoded signals is likely to be compromised by noise generated during signal transmission.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
