The number of cancer patients is rapidly increasing worldwide. Among the leading causes human death, can be regarded as one major threats to humans. Although many new treatment procedures such chemotherapy, radiotherapy, and surgical methods are nowadays being developed used for testing purposes, results show limited efficiency high toxicity, even if they have potential damage cells in process. In contrast, magnetic hyperthermia a field that originated from use nanomaterials, which, due their properties other characteristics, clinical trials solutions treatment. Magnetic nanomaterials increase temperature nanoparticles located tumor tissue by applying an alternating field. A very simple, inexpensive, environmentally friendly method fabrication various types functional nanostructures adding additives spinning solution electrospinning process, which overcome limitations this challenging Here, we review recently electrospun nanofiber mats support therapy, targeted drug delivery, diagnostic therapeutic tools, techniques

Biocompatible Ferrofluid Robot With Photothermal Property for Targeted Tumor Therapy

IEEE Robotics and Automation Letters, Год журнала: 2022, Номер 7(4), С. 11517 - 11522

Опубликована: Авг. 25, 2022

Magnetic-controlled micro-robots have promising applications in disease therapy due to their high targetability and drug utilization. Due unique deformable divisible properties, ferrofluid robots gained much attention microchemical reaction chips micromanipulation. This letter proposes a biocompatible robot validates its potential achieve targeted delivery tumor cell killing. ferrofluidic contains 10 nm oleic acid-coated ferric tetroxide particles vegetable oil has good magnetic responsiveness, deformability, photothermal can move liquid environments such as blood. It motion with an error of less than 0.4 mm under closed-loop control obstacle overturning passage through narrow channels twice diameter. In addition, the kill cells target area properties particles, experimental results show that death rate reach 95%. These capabilities give significant advantage getting location for cancer treatment vascular environment.

Adaptive PID Control Approach Considering Simulated Annealing Algorithm for Thermal Damage of Brain Tumor During Magnetic Hyperthermia

IEEE Transactions on Instrumentation and Measurement, Год журнала: 2023, Номер 72, С. 1 - 8

Опубликована: Янв. 1, 2023

Magnetic nanofluid hyperthermia (MNH) damages malignant cells by the heat generated magnetic nanoparticles (MNPs) exposed to an alternating field during therapy. The key point for is maintain treatment temperature a safe range bio-tissue, in which tissue will be damaged due its higher sensitivity but not healthy tissue. However, therapeutic system MNH should nonlinear one since generally determined many certain and uncertain factors, result difficulty modulate specific practical application. This study proposes control method introducing proportional–integral–derivative (PID) algorithm dynamically optimizes PID coefficients proposed considering simulated annealing (SA) distribution bio-tissue obtained solving improved Pennes bio-heat transfer equation using finite element (FEM). simulation results demonstrate that can effectively power dissipation MNPs further exactly regulate transient expected value. In addition, this also automatically adapt different cases therapy, concentration inside tumor region changes with injection strategy.

Preparing biological specimens for scanning electron microscopy (SEM) can be difficult to implement, as it requires specialized equipment and materials well the training of dedicated personnel. Moreover, procedure often results in damage samples analyzed. This work presents a protocol preparation evaluate adherence nanomaterials on cell surface using SEM. To this end, we used silicon wafers substrate grow cells replaced steps such critical point drying order make method quicker easier perform. The new was tested two different types cells, i.e., human osteosarcoma adipose-derived mesenchymal stem proved that grossly preserve integrity estimate nanomaterials' interaction with surfaces.

Biocompatible Ferrofluid‐Based Millirobot for Tumor Photothermal Therapy in Near‐Infrared‐II Window

Advanced Healthcare Materials, Год журнала: 2023, Номер 13(4)

Опубликована: Ноя. 10, 2023

Abstract Ferrofluidic robots with excellent deformability and controllability have been intensively studied recently. However, most of these studies are in vitro the use ferrofluids for vivo medicinal applications remains a big challenge. The application ferrofluidic to body requires solution many key problems. In this study, biocompatibility, controllability, tumor‐killing efficacy considered when creating ferrofluid‐based millirobot tumor‐targeted therapy. For biocompatibility problems, corn oil is used specifically ferrofluid robot. addition, control system built that enables 3D magnetic drive be implemented complex biological media. Using photothermal conversion property 1064 nm, robot can kill tumor cells vitro; inhibit volume, destroy interstitium, increase cell apoptosis, proliferation vivo. This study provides reference millirobots achieve targeted therapies
