Abstract

Methods and devices are provided for simultaneous irradiation of a target, such as mammalian cells and/or nanostructures. The target is simultaneously exposed to optical irradiation and oscillating magnetic field radiation. The simultaneous optical irradiation and oscillating magnetic field radiation occur within an incubator-actuator device. The incubator-actuator device includes a sample chamber, a magnetic field generating coil, and, a light-emitting diode (LED) placement cage.

Claims (20)

1. A method for irradiation of a mammalian cell, the method comprising:

exposing the cell to gold nanoparticle induced photo-thermal optical irradiation, wherein the gold nanoparticle induced photo-thermal optical irradiation has a laser power of 300 mW; and

simultaneously exposing the cell to oscillating magnetic field radiation, wherein the magnetic field has an intensity of from 40 Oe to 60 Oe and wherein the magnetic field has a frequency of 120 kHz;

wherein the simultaneous photo-thermal optical irradiation and oscillating magnetic field radiation occur within an incubator-actuator device.

2. The method of claim 1 , wherein the device comprises a sample chamber, a magnetic field generating coil, and a light-emitting diode (LED) placement cage.

3. The method of claim 1 , wherein the gold nanoparticle induced photo-thermal optical irradiation occurs at a wavelength between about 450 nm to about 675 nm.

4. The method of claim 1 , wherein simultaneously exposing the cell comprises simultaneously initiating both the gold nanoparticle induced photo-thermal optical irradiation and the oscillating magnetic field radiation.

5. A method for irradiation of a nanostructure, the method comprising:

exposing the nanostructure to gold nanoparticle induced photo-thermal optical irradiation, wherein the gold nanoparticle induced photo-thermal optical irradiation has a laser power of 300 mW; and

simultaneously exposing the cell to oscillating magnetic field radiation, wherein the magnetic field has an intensity of from 40 Oe to 60 Oe and wherein the magnetic field has a frequency of 120 kHz;

wherein the simultaneous photo-thermal optical irradiation and oscillating magnetic field radiation occur within an incubator-actuator device.

6. The method of claim 5 , wherein the device comprises a sample chamber, a magnetic field generating coil, and a light-emitting diode (LED) placement cage.

7. The method of claim 5 , wherein the gold nanoparticle induced photo-thermal optical irradiation occurs at a wavelength between about 450 nm to about 675 nm.

8. The method of claim 5 , wherein the nanostructure comprises a shell encapsulating at least one nanoparticle.

9. The method of claim 8 , wherein the shell comprises a material selected from the group consisting of polyvinylpyrrolidone (PVP), polyethylene glycol (PEG) and derivatives thereof, poly(N-isopropylacrylamide), tannic acid, dextran, dimercaptosuccinic acid (DMSA) and combinations thereof.

10. The method of claim 8 , wherein the at least one nanoparticle is at least one magnetic nanoparticle selected from the group consisting of gold, ferric oxide, magnetite, maghemite, gadolinium-doped cobalt ferrite, and combinations thereof.

11. The method of claim 8 , wherein the shell has a thickness of from about 2 nm to about 200 nm.

12. The method of claim 8 , wherein the at least one nanoparticle has a size of from about 5 nm to about 100 nm.

13. The method of claim 8 , wherein the at least one nanoparticle has a diameter of from about 5 nm to about 270 nm.

14. The method of claim 5 , wherein simultaneously exposing the nanostructure comprises simultaneously initiating both the gold nanoparticle induced photo-thermal optical irradiation and the oscillating magnetic field radiation.
