Iron oxide nanoparticle-based radio-frequency thermotherapy for human breast adenocarcinoma cancer cells.

Iron oxide nanoparticles (IONPs) with diameters of 15, 25, and 41 nm were evaluated as mediators of thermal cytotoxicity under radio-frequency (RF) exposure. The 25 nm IONPs were found to be the most efficient of the three in killing cancer cells at 350 kHz low-frequency RF irradiation. However, at a higher frequency of 13.

Exceptional superhydrophobicity and low velocity impact icephobicity of acetone-functionalized carbon nanotube films.

We present a simple method to produce carbon nanotube-based films with exceptional superhydrophobicity and impact icephobicity by depositing acetone-treated single-walled carbon nanotubes on glass substrates. This method is scalable and can be adopted for any substrate, both flexible and rigid. These films have indicated a high contact angle, in the vicinity of 170°, proved both by static and dynamic analysis processes.
