Correlative intravital imaging of cGMP signals and vasodilation in mice
Frontiers in Physiology, 2014 Cyclic guanosine monophosphate (cGMP) is an important signaling molecule and drug target in the cardiovascular system. It is well known that stimulation of the vascular nitric oxide (NO)-cGMP pathway results in vasodilation.

A FRET-Based Calcium Biosensor with Fast Signal Kinetics and High Fluorescence Change [PDF]
Biophysical Journal, 2006 Genetically encoded calcium biosensors have become valuable tools in cell biology and neuroscience, but some aspects such as signal strength and response kinetics still need improvement. Here we report the generation of a FRET-based calcium biosensor employing troponin C as calcium-binding moiety that is fast, is stable in imaging experiments, and ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

An ATP-Driven N Protein-DDX21 Molecular Switch Dynamically Controls SARS-CoV-2 RNA G-Quadruplex Heterogeneity. [PDF]
Adv Sci (Weinh)An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

Interpreting Crowding Effects on FRET Signals for Protein Kinetics Analysis [PDF]
In biological studies in vitro and in vivo, techniques involving Förster resonance energy transfer (FRET) and FRET quantification use the interaction of CyPet-SUMO1 and its E2 ligase, YPet-Ubc9, to determine the dissociation constant (KD).

Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.
