Mechanism and applications of magnetoelectric nanoparticles in cancer therapy

Area of Science:

• Nanomedicine
• Materials Science
• Oncology

Background:

• Conventional cancer therapies face challenges like off-target effects, drug resistance, and incomplete tumor eradication.
• There is a critical need for advanced, precise, and effective cancer treatment strategies.
• Magnetoelectric nanoparticles (MENPs) are emerging as a promising solution in nanomedicine for cancer treatment.

Purpose of the Study:

• To review the mechanisms and applications of magnetoelectric nanoparticles (MENPs) in cancer therapy.
• To explore recent advances in MENP synthesis, material optimization, and preclinical efficacy.
• To highlight the potential of MENPs for precision oncology and overcoming limitations of current treatments.

Main Methods:

• Literature search of electronic databases (PubMed, Web of Science, Scopus, Google Scholar) using relevant keywords.
• Analysis of studies on MENP synthesis, material composition, and morphology.
• Review of preclinical data on MENP-mediated cancer treatment, including drug delivery, cell membrane disruption, and tumor regression.

Main Results:

• MENPs, typically core-shell structures of magnetostrictive and piezoelectric materials, generate electric fields under magnetic stimulation.
• Preclinical studies demonstrate MENPs enhance targeted drug delivery, disrupt tumor cell membranes, and induce tumor regression.
• MENPs show potential for non-invasive, targeted cancer therapy with minimal systemic toxicity.

Conclusions:

• MENPs represent a promising platform for precision oncology, offering remote control over therapeutic effects.
• The unique magnetoelectric properties of MENPs can overcome limitations associated with conventional cancer treatments.
• Further research focusing on optimizing MENP design, selectivity, efficacy, and clinical translation is crucial for their advancement in cancer therapy.
