Nanoclusters comprising inorganic nanocrystals and a biodegradable polymer are disclosed. The inorganic nanocrystals have a mean particle size of 1 to 500 nm. The inorganic nanocrystals are contained within a core of the nanoclusters, on the surface of the nanoclusters, contained within a core of the nanoclusters, dispersed throughout the nanoclusters, or a combination thereof. The biodegradable polymer allows the inorganic nanocrystals to be excreted renally over a period of time. The nanoclusters can be used for medical imaging or other biomedical applications.

Harvested stem cells are activated by treating them with an amplitude modulated laser beam having a wavelength lying in the range of 405 to 980 nanometers. The frequency of the laser beam is modulated within a range of 8 to 12 MHz. Using the activated stem cells, tissue can be repaired and regenerated by preparing the unactivated stem cells, treating the unactivated stem cells with an amplitude modulated laser beam having a pre-determined frequency for obtaining activated stem cells, administering the activated stem cells into a body containing the tissue, and using a homing beam to guide the activated stem cells within the body to the location of the tissue.

A system includes a control device and a magnetic device coupled to the control device. The magnetic device is configured to inductively couple to a treatment target including one or more cells exposed to an agent, and includes one or more magnetic coils. The control device and the magnetic device are collectively configured to generate and apply a transient magnetic field to the treatment target to induce an electric field and porate the one or more cells and to permit the agent to enter the one or more cells.

Provided is a method of reducing a number of viable microbes, including contacting microbes with an antibiotic compound and applying pulses of electricity having a duration of between about 50 nanoseconds and about 900 nanoseconds. The pulses of electricity may have an intensity between about 20 kV/cm and about 40 kV/cm. The pulses of electricity may be applied at a frequency of between about 0.1 Hz and about 10 Hz. The microbes may be a gram-negative or a gram-positive strain of bacteria and the antibiotic may be applied at a concentration for a duration, wherein applying the antibiotic to the strain at the concentration for the duration does not reduce a viable number of bacteria of the strain as much, or at all, when the pulses of electricity are not also applied.

A stem cell therapy using an energy field (e.g., a laser beam) to prime stem cells, and then using a matching energy field to direct the primed stem cells to a target tissue. Preferably, the matching energy field has the same frequency as the energy field use to prime the stem cells (with no more than 10 Hz variation). Stem cells can be primed ex vivo or in vivo, by being exposed to the energy field, and/or a growth hormone. The stem cell therapy can be used to treat diseases including heart disease, spinal cord injury, and neurodegenerative diseases.

Methods for the generation of electrochemical plasma activated aqueous chemotherapeutics (EPAAC) solutions are described. These solutions have been found to selectively reduce the proliferation of human pancreatic cancer cells, with no toxic effects for healthy cells.
