Metasurface-empowered snapshot hyperspectral imaging with convex/deep (CODE) small-data learning theory
Design of multi-resonant meta-atom for multi-wavelength off-axis focusing meta-mirror The main idea for constructing a multispectral image of a color object without involving filters is utilizing a multi-resonant meta-atom as the metasurface building block. We incorporate an Al nano-rod with a particularly designed distributed Bragg reflector (DBR) to realize a multi-resonant meta-atom. Details of the…

Nano-scale charge trapping memory based on two-dimensional conjugated microporous polymer
We conducted a series of current scans using the cAFM, operating in contact mode, with dimensions of 2.5 × 2.5 µm2. The scans were carried out as follows: a read scan was performed at 0.5 V (Fig. 6a), a write scan was done at 5 V (Fig. 6b), followed by another read scan at 0.5 V (Fig. 6c), an erase scan was executed…

MXene-enhanced plasmonic sensing for ultrasensitive label-free miRNA detection
Oct 31, 2023 (Nanowerk News) microRNAs (miRNAs) are small non-coding RNA molecules that play an important role in the development and progression of various types of cancer, which makes it as biomarkers. The detection of miRNAs is of vital importance to the early-stage diagnostics and prognostics. However, traditional detection strategies for miRNAs have faced the…
