Magnetic nanoparticles (MNPs) have been widely investigated as a hyperthermic agent for cancer treatment. In this study, thermally responsive Chitosan-coated MnFe2O4 (Chitosan-MnFe2O4) were developed to conduct localized magnetic hyperthermia Hydrophobic synthesized via thermal decomposition and modified with 2,3-dimercaptosuccinic acid (DMSA) further conjugation of chitosan. Chitosan-MnFe2O4 exhibited high magnetization excellent biocompatibility along low cell cytotoxicity. During...
This work aims to produce and optimize a κ-carrageenan-based nanoemulsion (NE) encapsulate seaweed oil, which is rich in fucoxanthin (FX), using ultrasound-assisted emulsification. κ-Carrageenan was produced subcritical water, oil extracted supercritical carbon dioxide with sunflower as the co-solvent. Response surface methodology (RSM) used understand influence of several process parameters such ultrasound amplitude, time, temperature, duty cycle an NE. The RSM factor focus on droplet size,...
The purpose of this study was to investigate the effect optical pulse duration on stone retropulsion during Ho:YAG (lambda = 2.12 microm) laser lithotripsy.A clinical with durations employed fragment calculus phantoms and evaluate phantom retropulsion. At a given energy, were divided into two discrete conditions: short (tau(p): 120 approximately 190 microseconds at FWHM) long 210 350 FWHM). Plaster Paris ablated different energy levels using fibers varying diameters (273, 365, 550 microm in...
Laser ablation of aluminum metal with 1ns, 800nm pulse at low radiant exposures was investigated in air (dry) and water (wet) environments. Compared to dry ablation, an approximately eight times increase material removal rate associated wet ablation. Based on optical reflectance scanning electron microscope images, bubble formation/collapse responsible for augmented acoustic pressure performance. Numerically simulated temperature distributions during were consistent the occurrence explosive...
We demonstrate the feasibility of mapping a sentinel lymph node (SLN) and urinary bladder by using modified single-walled carbon nanotubes (SWNTs) as nonionizing photoacoustic (PA) contrast agent. To improve PA sensitivity, indocyanine green (ICG) was conjugated with SWNTs optical absorption SWNTs-ICG enhanced approximately four times compared to that plain at concentration 0.3 µM. In vivo imaging results showed SLN were clearly visualized due accumulation SWNTs-ICG. This implies could be...
The current research demonstrates the feasible biomedical application of AuNPs coated with doxorubicin (Dox)-loaded fucoidan (Fu) for dual-chemotherapy and photothermal treatment (PTT) on eye tumors in vitro vivo. Marine-derived Fu was used as a capping agent to achieve high photostability AuNPs, Dox FDA-approved anti-cancer drug added induce chemotherapy. synthesized Dox-Fu@AuNPs exhibited cytotoxicity tumor cells strong light absorption temperature increase vitro. After intratumoral...
With the advancement of nanotechnology, several nanoparticles have been synthesized as antimicrobial agents by utilizing biologically derived materials. In most cases, materials used for synthesis from natural sources are extracts. Natural extracts contain a wide range bioactive components, making it difficult to pinpoint exact component responsible nanoparticle synthesis. Furthermore, present in extract changes according numerous environmental factors. As result, current work intended...
Stress urinary incontinence (SUI) is a prominent caused by increased abdominal pressure. Sling treatments are surgical procedures used to treat SUI inserting an artificial mesh into the urethra. However, after sling treatments, patients can be at risk of chronic pain and infection in urological system. The current research aims develop new non-ablative transurethral laser treatment for as minimally invasive non-implantable procedure. Six females porcine were randomly divided three groups:...
