Theory of Cylindrical Tubules and Helical Ribbons of Chiral Lipid Membranes

open access: yes, 1995
We present a general theory for the equilibrium structure of cylindrical tubules and helical ribbons of chiral lipid membranes. This theory is based on a continuum elastic free energy that permits variations in the direction of molecular tilt and in the ...

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

open access: yesAdvanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Glucocorticoid receptor gene inactivation in dopamine-innervated areas selectively decreases behavioral responses to amphetamine

open access: yesFrontiers in Behavioral Neuroscience, 2014
The meso-cortico-limbic system, via dopamine release, encodes the rewarding and reinforcing properties of natural rewards. It is also activated in response to abused substances and is believed to support drug-related behaviors.

Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

open access: yesAdvanced Materials, EarlyView.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...

Gene Expression and Molecular Characterization of a Xylanase from Chicken Cecum Metagenome

open access: yesInternational Journal of Microbiology, 2017
A xylanase gene xynAMG1 with a 1,116-bp open reading frame, encoding an endo-β-1,4-xylanase, was cloned from a chicken cecum metagenome. The translated XynAMG1 protein consisted of 372 amino acids including a putative signal peptide of 23 amino acids ...

Dual‐Selective Terahertz‐Nanodisc Metasurfaces for Exploring Neurotransmitter Dynamics beyond Spectral Limitations

open access: yesAdvanced Materials, EarlyView.
Observation and detection of neurotransmitter dynamics in aqueous system has been hurdle for analytical fields due to its weak and reversible nature. A terahertz‐nanodisc metasurface which implements comprehensive detection over conformational change and selective sensing is introduced. Utilizing the THz regime photonics and biomimetic environment with

Exploring Polydioxanone as a Substrate for Fully Resorbable Implantable Sensors

open access: yesAdvanced Sensor Research, EarlyView.
Polydioxanone (PDO) is explored as a substrate for fully resorbable implantable sensors. Using screen‐printing and special formulated zinc and PEDOT:PSS inks, temperature and conductivity sensors, organic electrochemical transistors and antennas are fabricated and characterized directly on PDO.
