Dielectric metasurfaces and their applications for optical biosensing
Over the past century, our understanding of life has been focused on its most fundamental building blocks: molecules. Biological molecules, such as proteins found in blood, other body fluids, or tissues, are excellent guides to identifying a normal or abno ...
EPFL2023Dielectric Tetramer Nanoresonators Supporting Strong Superchiral Fields for Vibrational Circular Dichroism Spectroscopy
Hatice Altug, Felix Ulrich Richter, Yasaman Jahani, Rui Lu, Bang Hyun Lee, Ming-Lun Tseng, Longfang Ye
Chirality (C) is a fundamental property of objects, in terms of symmetry. It is extremely important to sense and distinguish chiral molecules in the fields of biochemistry, science, and medicine. Vibrational circular dichroism (VCD) spectroscopy, obtained ...
Washington2023Dendrimer-Based Coatings on a Photonic Crystal Surface for Ultra-Sensitive Small Molecule Detection
We propose and demonstrate dendrimer-based coatings for a sensitive biochip surface that enhance the high-performance sorption of small molecules (i.e., biomolecules with low molecular weights) and the sensitivity of a label-free, real-time photonic crysta ...
MDPI2023Extreme Spatial Dispersion in Nonlocally Resonant Elastic Metamaterials
Romain Christophe Rémy Fleury, Aleksi Antoine Bossart
To date, the vast majority of architected materials have leveraged two physical principles to control wave behavior, namely, Bragg interference and local resonances. Here, we describe a third path: structures that accommodate a finite number of delocalized ...
2023New Sensing Technologies for Monitoring Machinery, Structures, and Manufacturing Processes
Sensing is the fundamental technique for sensor data acquisition in monitoring the operation condition of the machinery, structures and manufacturing processes. In this paper, we briefly discuss the general idea and advances of various new sensing technolo ...
2023Metasurface-Enhanced Infrared Spectroscopy: An Abundance of Materials and Functionalities
Hatice Altug, Felix Ulrich Richter, Andreas Tittl, Aurélian Michel John-Herpin
Infrared spectroscopy provides unique information on the composition and dynamics of biochemical systems by resolving the characteristic absorption fingerprints of their constituent molecules. Based on this inherent chemical specificity and the capability ...
WILEY-V C H VERLAG GMBH2022Effect of mechanical nonlinearity on the electromagnetic response of a microwave tunable metamaterial
Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Rayehe Karimi Mahabadi, Taha Goudarzi
Tunable metamaterials functionalities change in response to external stimuli. Mechanical deformation is known to be an efficient approach to tune the electromagnetic response of a deformable metamaterial. However, in the case of large mechanical deformatio ...
IOP Publishing Ltd2022Real-time monitoring of single-cell secretion with a high-throughput nanoplasmonic microarray
Hatice Altug, Xiaokang Li, Yen-Cheng Liu, Saeid Ansaryan, Eduardo Romero Arvelo
Proteins secreted by cells play significant roles in mediating many physiological, developmental, and pathological processes due to their functions in intra/intercellular communication and signaling. Conventional end-point methods are insufficient for unde ...
2022Surface Plasmon Effect Dominated High-Performance Triboelectric Nanogenerator for Traditional Chinese Medicine Acupuncture
Available, effectively converting low-frequency vibration into available electricity, triboelectric nanogenerator (TENG) is always research hot nowadays. However, the enhancing effect of the existing methods for the output have all sorts of drawbacks, i.e. ...
AMER ASSOC ADVANCEMENT SCIENCE2022Quantitative and sensitive detection of alpha fetoprotein in serum by a plasmonic sensor
Tianzong Zhang, Wen Chen, Fei Gao
Quantitative molecular detection based on surface-enhanced Raman spectroscopy (SERS) is still a great challenge because of the highly nonuniform distribution of the SERS hot spots and the nondeterministic spatial and spectral overlap of the analyte with th ...
