Gold coated silica core nanoparticles have an optical response dictated by the plasmon resonance. The wavelength at which the resonance occurs depends on the core and shell sizes, allowing nanoshells to be tailored for particular applications. The purposes of this study was to synthesize and use different concentration of gold nanoshells as exogenous material for skin tissue soldering and also ...

The unprecedented growth in the telecommunications sector in the mid to late 1990’s saw a high demand in the area of optical packages and optical networks. This sudden growth in demand for optical technology in telecom and data communication applications could not be supported by the existing manufacturing infrastructure; so, to meet the growing volume needs of the industry – the electronics ma...

OBJECT The goal of this study was to use a modified version of the CO2 laser-soldering system to develop a simple and reliable technique for the repair of dural defects after excision of brain tumors. METHODS The authors used a CO2 fiber optic laser system that they had developed for heating, monitoring, and controlling tissue temperature in situ and in real time, thereby reducing damage to t...

AIM To explore the feasibility and reliability of CO₂ laser soldering on the reconstruction of dura mater in the minipig model. MATERIAL AND METHODS Ten minipigs were divided into 2 groups as Group A (n=5) and Group B (n=5). Bilateral fronto-parietal craniotomy was performed and 2 cm × 1 cm dural defect created under general anesthesia. Then, the defect was repaired with autologous temporalis...

We described the synthesis of Au coated SiO2 nanoshells linked with NH2 biomolecular ligands using a simple wet chemical method with a particular application for laser tissue soldering. Tunable nanoshells were prepared by using different gold colloidal concentrations. The nanoshells are characterized by UV-vis spectroscopy, FTIR, XRD and AFM. The FTIR results confirmed the functionalized surfac...

Conventional soldering typically requires fluxing to promote wetting. Halogenated solvents must then be used to remove the flux residues. While such practice has been routinely accepted throughout the DOE weapons complex, new environmental laws and agreements will eventually phaseout the use of these solvents. Solvent substitution or alternative technologies must be developed to meet these rest...

The Discrete Ordinates Method (DOM) for solving transient radiation transfer equation in cylindrical coordinates is developed for radiation heat transfer in participating turbid media in pico-scale time domain. The application problems addressed here are laser tissue welding and soldering. The novelty of this study lies with the use of ultrashort laser pulses as the irradiation source. The char...
