For decades now, conventional sinusoidal signals have been exclusively used in magnetic hyperthermia as the only alternating field waveform to excite nanoparticles. However, there are no theoretical nor experimental reasons that prevent use of different waveforms. The justifiable motive behind using signal is its availability and facility produce it. Following development a configurable generator, we aim study effect various waveforms on heat production effectiveness nanoparticles, seeking...
This article shows the use of a high-frequency Full-Bridge inverter to design an alternating magnetic field generator for experimental studies on anti-cancer treatment with nanoparticles. In hyperthermia, nanoparticles are used raise pathological cancerous cell's temperature high enough induce their death by apoptosis, but not as destroy them thermal ablation whole tissue volume, consequently leaving healthy cells alive. Conventionally, sinusoidal fields heat nanoparticles, which can be more...
Viscosity variation in human fluids, such as Synovial Fluid (SF) or Cerebrospinal (CSF), can be used a diagnostic factor; however, the sample volume obtained for analysis is usually small, making it difficult to measure its viscosity. On other hand, Quartz Crystal Resonators (QCR) have been widely sensing applications due their accuracy, cost, and size. This work provides design validation of new viscosity measurement system based on quartz crystal resonators low leading development sensor...
Although optical hyperthermia could be a promising anticancer therapy, the need for high concentrations of light-absorbing metal nanoparticles and high-intensity lasers, or large exposure times, discourage its use due to toxicity that they imply. In this article, we explore possible role silica microparticles have biocompatibility scatter light, when used in combination with conventional nanoparticles, reduce those particles and/or intense laser beams, order improve overall procedure. Our...
