We are pioneering nanotechnology-driven treatments for late-stage skin cancers, addressing critical challenges in targeting, efficacy, and safety. Our research focuses on two cutting-edge platforms: Electromagnetically Actuated “Nano-Star” Systems and Magneto-Photothermal Nanoplatforms.

The first and most foundational component of our therapeutic approach lies in the deployment of magnetically actuated nanoparticles. These particles operate through a polarization-dependent behavior, oscillating between coupled and decoupled states, with movement directed by internal magnetization properties. Their activity is finely modulated using external magnetic and electric fields.

Our star patterned architecture builds on this principle by integrating chains of biodegradable nanorobots, designed for targeted locomotion and force application within tumor environments. Under low-frequency varying magnetic fields (typically <100 Hz), these nanochains engage in controlled oscillations, generating mechanical shear forces that compromise cancer cell integrity. Unlike thermal-based ablation, this approach minimizes off-target heating and reduces collateral damage to surrounding tissues.

In parallel, these particles are surface-functionalized with immunologically active components, such as tumor-associated antigens (e.g., OVA protein), transforming the tumor site into a local immunogenic depot. This triggers a robust antigen-presenting cell response, leading to T-cell priming and systemic anti-tumor immunity. Moreover, these systems demonstrate the ability to locally modulate tumor acidity, a factor known to impair immune cell function, thereby enhancing infiltration and activity of cytotoxic immune populations. In contrast, our second platform—the Magneto-Photothermal Nanoplatform—leverages the synergistic combination of magnetic hyperthermia and photothermal activation. These dual-function nanostructures feature an iron oxide core, selected for its high magnetic susceptibility, enveloped by a gold nanostar shell engineered for peak NIR absorption. When exposed to alternating magnetic fields, the core initiates internal heating through magnetic relaxation mechanisms, while concurrent NIR laser irradiation excites the gold shell via plasmonic resonance, resulting in highly localized thermal ablation.

This dual-thermal strategy yields thermally confined cytotoxic zones with minimal impact on adjacent skin structures. Additionally, the nanoparticles are compatible with MRI and photoacoustic imaging modalities, providing real-time visibility and spatial control during treatment. In preclinical murine models, this approach has demonstrated significant tumor volume reduction, enhanced vascular permeability, and increased responsiveness to adjuvant chemo- and radiotherapies. Both nanotherapy systems offer modular integration with existing oncology frameworks. The Linked Nano-Star system provides a mechanical-immune axis, ideally suited for immunotherapeutic synergy and metastatic clearance. Meanwhile, the Magneto-Photothermal platform offers a thermally focused ablation method, scalable for precision outpatient procedures in drug-resistant or anatomically complex cutaneous tumors.
