SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, Volume 22, Issue 28, 18 May 2026.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Tunable ring resonator filter for OFDM Transmission systems [PDF]

, 1995
A novel tunable filter is theoretically demonstrated. It is based on a ring resonator with an amplifier and a noise filter in the loop. This optoelectronic device has potential as a high-sensitivity receiver and as a tunable demultiplexer in OFDM ...

A Gas Sensor Based on Fully Tuneable and Electrically Coupled Bulk Acoustic Wave Resonators

Proceedings
This paper reports on a gas sensor based on two bulk acoustic wave (BAW) resonators electrically coupled with a tuneable capacitor. The weak coupling strength was tuned to its optimal value (achieving maximum sensitivity) by varying the capacitance ...
