Background:

Externally modulated nanoparticles represent an emerging class of cancer nanotherapeutics.
These agents combine passive tumor accumulation with external control over therapy delivery.
They offer potential for enhanced therapeutic efficacy and reduced off-target effects.

Purpose of the Study:

To classify externally modulated theranostic nanoparticles based on external control modes.
To describe the underlying physicochemical mechanisms of external control.
To illustrate nanoparticle embodiments with proven biological efficacy.

Main Methods:

Review and classification of nanoparticles based on external modulation (optical, magnetic, ultrasound).
Analysis of physiochemical mechanisms governing external control of therapy.
Illustration of specific nanoparticle systems and their biological applications.

Main Results:

Electromagnetic radiation (visible/near-infrared) utilizes gold/carbon nanostructures for imaging and photothermal therapy (PTT).
Magnetic field manipulation employs iron-oxide nanostructures for magnetic resonance imaging (MRI) and magnetothermal therapy.
Ultrasound methods primarily enhance the delivery of nanotherapeutics to tumor sites.

Conclusions:

Externally modulated theranostic nanoparticles offer precise spatio-temporal control over cancer therapy.
These agents provide theranostic capabilities, integrating diagnostics and therapeutics.
Diverse nanoparticle platforms are being developed for various external modulation strategies in cancer treatment.
