Plasmonic Nanocomposite Implants for Interstitial Thermotherapy: Experimental and Computational Analysis

Surface modification for titanium implants by hydroxyapatite nanocomposite

Background: Titanium (Ti) implants are commonly coated with hydroxyapatite (HA). However, HA has some disadvantages such as brittleness, low tensile strength and fracture toughness. It is desirable to combine the excellent mechanical properties of ZrO2 and the chemical inertness of Al2O3 with respect to the purpose of this project which was coating Ti implants with HA-ZrO2-Al2O3 to modify the s...

Evaluation of Temperature Rise and Thermal Lesion Dimensions in Liver Laser Interstitial Thermotherapy

Introduction:  Laser  interstitial  thermotherapy  (LITT)  is  an  internal  ablation  therapy  method  consisting of a percutaneous or intraoperative insertion of laser fibers directly into the liver tumor with  maximum diameter of 5 cm. In this treatment method, there isn’t any general information about the  relationship  between  increasing  the  exposure  power,  coagulation  and  carboniza...

Review of Plasmonic Nanocomposite Metamaterial Absorber

Plasmonic metamaterials are artificial materials typically composed of noble metals in which the features of photonics and electronics are linked by coupling photons to conduction electrons of metal (known as surface plasmon). These rationally designed structures have spurred interest noticeably since they demonstrate some fascinating properties which are unattainable with naturally occurring m...

Gold-Poly(methyl methacrylate) Nanocomposite Films for Plasmonic Biosensing Applications

Gold-poly(methyl methacrylate) nanocomposites are prepared by an in situ method, by irradiating spin-coated films containing the polymer and the gold precursor dissolved in acetone. The reduction of gold ions results in the formation of Au that nucleates and grows within the polymer film. It is shown that, depending on the energy source, gold nanoparticles with different shapes can be formed. N...
