Advanced Functional Materials, Volume 34, Issue 37, September 11, 2024.Information can be encoded onto a fluorescent polymer via facile ultraviolet light exposure. The inscriptions can be written as a single color or in a polychromic format. The polymer can then be removed from the substrate as a freestanding, flexible, transparent film.

Electrochemical Surface Plasmon Resonance Sensing using a van der Waals Heterostructure
Advanced Sensor Research, Volume 3, Issue 9, September 2024.Here a new strategy is presented to realize an electrochemical surface plasmon resonance (EC‐SPR) sensor using a graphene/hexagonal boron nitride heterostructure on gold. With this sensor, it is shown that the potential‐dependent modulation of the EC‐SPR signal on gold can be completely suppressed, enabling unambiguous monitoring of redox reactions at ...

Using Fluorescent GAP Indicators to Monitor ER Ca2+
Current Protocols, Volume 4, Issue 6, June 2024.Abstract The endoplasmic reticulum (ER) is the main reservoir of Ca2+ of the cell. Accurate and quantitative measuring of Ca2+ dynamics within the lumen of the ER has been challenging. In the last decade a few genetically encoded Ca2+ indicators have been developed, including a family of fluorescent Ca2+ indicators, dubbed GFP‐Aequorin Proteins (GAPs).

Segmentation-Aware and Adaptive Iris Recognition [PDF]
arXiv, 2019 Iris recognition has emerged as one of the most accurate and convenient biometric for the human identification and has been increasingly employed in a wide range of e-security applications. The quality of iris images acquired at-a-distance or under less constrained imaging environments is known to degrade the iris matching accuracy.

Iris Recognition With Off-the-Shelf CNN Features: A Deep Learning Perspective
IEEE Access, 2018 Iris recognition refers to the automated process of recognizing individuals based on their iris patterns. The seemingly stochastic nature of the iris stroma makes it a distinctive cue for biometric recognition.
