Chitosan nanoparticles are emerging as promising vaccine carriers that may improve antigen stability, mucosal delivery, immune activation, and thermostability for needle-free immunization. The review highlights how chemical modification, fabrication methods, and quality control could advance scalable vaccine platforms, while emphasizing that clinical translation is still early.

Researchers developed a PFAS- and NMP-free cellulose nanofibril binder that improves dispersion, adhesion, ion transport, and structural integrity in high-loading lithium-ion battery positive electrodes. The binder enabled NCM811 electrodes with high mass loading, strong areal capacity, and improved cycling stability, suggesting a more sustainable route to high-energy battery ma...

Researchers developed printable 3D achromatic metalenses using grayscale electron beam lithography, dry etching, and nanoimprint lithography to control nanoscale height and shape. The metalenses focused red, green, and blue light at nearly the same plane and enabled proof-of-concept full-color OLED near-eye VR imaging with reduced chromatic blur.

Researchers developed a “talkative battery” that transmits internal and external temperature data through existing power connections using load shift keying. While validated with NTC-based sensing, the method could also support future nano-enabled sensors printed or embedded inside large-format lithium-ion cells.

PI, a global leader in precision motion control and air bearing positioning systems, offers the A-123 air bearing linear slide, a high-performance air bearing linear translation stage designed for ultra-precise scanning, metrology, inspection, and nanopositioning applications.
