Introduction: Photothermal therapy using gold nanoshells is one of cancer therapy methods. Gold nanoshells generally consist of a silica core and a thin gold shell. Fe3O4@Au core-shell can be used for magnetic targeted therapy. The objective of this study was investigation of the photothermal effects of magnetically targeted Fe3O4@Au NPs and NIR laser irradiation on model of me...

We present the experimental results for scattering intensity which arises from illumination of turbid medium with laser light for characterizing the different types of particles. The imaging of tissue like phantom provides the possibility of modeling the laser tissue interaction parameters for the diagnostic of malignant disease and determining the optical properties of a material. Analytical m...

The outwardly directed cell wall and associated plasma membrane of epidermal cells represent the first layers of plant defense against intruding pathogens. Cell wall modifications and the formation of defense structures at sites of attempted pathogen penetration are decisive for plant defense. A precise isolation of these stress-induced structures would allow a specific analysis of regulatory m...

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...

background: the effectiveness of low power lasers on incisional wound healing, because of confl icting results of previous studies, is uncertain. therefore, the aim of this study was to evaluate the effects of low-level helium-neon (he-ne) laser irradiation on wound healing in rat’s oral mucosa. materials and methods: sixty-four standardized incisions were carried out on the buccal mucosa of 32...

The noninvasiveness of nonlinear optical imaging techniques is quantified in terms of the number of free electron generated in the laser-tissue interaction region per photon emitted into the nonlinear optical signal. For a broad variety of biomarker dyes and bioactivity reporter proteins, this ratio is shown to approach a critical value of unity for field intensities above 1 TW/cm2. Closed-form...
