Scientists Revolutionize Liver Cancer Treatment with Magnetic Microrobots

In an exciting development from Canada, Dr Gilles Soulez and his team have unveiled a revolutionary technique to change how liver tumours are treated. This cutting-edge method involves tiny, magnetically steerable microrobots within an MRI machine, offering a fresh perspective on medical treatments.

For years, the idea of employing minuscule robots to aid in healing within the human body has been a topic of fascination. These aren't just figments of science fiction; they are authentic, tiny, biocompatible machines made from magnetisable iron oxide nanoparticles. The beauty of these microrobots lies in their ability to be directed by external magnetic fields, allowing for targeted treatment delivery.

One of the main obstacles encountered in the past was the issue of gravity overpowering the magnetic forces intended to guide these robots. This was particularly problematic when reaching tumours above the injection site in the bloodstream. Despite the powerful magnetic fields generated by MRI machines, the gradients needed for navigation and imaging were insufficiently robust.

Dr. Soulez, who is associated with the CHUM Research Center and leads the Department of Radiology, radio-oncology, and Nuclear Medicine at the Université de Montréal, shared his team’s innovative solution to overcome this hurdle. "To solve this problem, we developed an algorithm that determines the position that the patient's body should be in for a clinical MRI to take advantage of gravity and combine it with the magnetic navigation force," he explained. This strategic approach helps direct the microrobots to the arterial branches feeding the tumour, improving the precision of treatment delivery.

The new technique signifies a shift in interventional radiology practices for treating liver cancer. Hepatocellular carcinoma, a common type of liver cancer, causes around 700,000 deaths annually worldwide. Traditionally, treatment involves transarterial chemoembolisation, a complex process where chemotherapy is directly delivered to the liver tumour's feeding artery, and the tumour's blood supply is blocked using microcatheters under X-ray guidance.

Dr. Soulez noted the benefits of magnetic resonance navigation, noting its compatibility with the implantable catheters used in chemotherapy. He emphasised the advantage of MRI over X-ray imaging in tumour visualisation, suggesting significant potential for this method in clinical applications.

The research team's collaboration with Sylvain Martel from Polytechnique Montreal and Urs O. Häfeli from the University of British Columbia has been pivotal in advancing this field. Ning Li, a postdoctoral fellow in Dr Soulez's laboratory and the study's first author, played a vital role in the research.

A key innovation was the development of an MRI-compatible microrobot injector, which assembles "particle trains"—clusters of these magnetisable microrobots that exhibit increased magnetic force, making them easier to navigate and detect in MRI scans.

To ensure the method's efficacy, the team conducted trials on 12 pigs, aiming to replicate human anatomical conditions as closely as possible. These trials confirmed the microrobots' capability to navigate to specific hepatic artery branches and reach their intended destinations, as the newly developed algorithm directed.

Additionally, the team utilised an anatomical atlas of human livers to simulate microrobot navigation in 19 patients previously treated with transarterial chemoembolisation, encompassing thirty tumours in different parts of the liver. The simulations indicated that the navigation algorithm was effective in over 95% of cases, allowing the microrobots to reach the targeted tumours successfully.

Despite these promising results, Dr. Soulez cautioned that the clinical adoption of this technology is still some way off. The following steps involve refining the real-time navigation of the microrobots using artificial intelligence, which would entail tracking the microrobots' location within the liver and identifying blockages in the hepatic artery branches that supply the tumour.

The team also develops models to simulate blood flow, patient positioning, and magnetic field direction. These models, created with fluid flow simulation software, will help determine how these factors affect the microrobots' journey to the tumour, thereby improving the treatment's accuracy and effectiveness.

This breakthrough by Dr. Soulez and his team represents a transformative approach to treating liver cancer, employing magnetically controlled microrobots to deliver therapy with unparalleled precision. By ingeniously merging gravitational and magnetic forces through a unique algorithm, this method promises increased treatment efficacy while minimising harm to healthy cells. However, the journey to clinical practice requires further advancements, particularly in the real-time navigation of the microrobots, which the team hopes to achieve with the help of artificial intelligence.

The Cryogenic Innovation Enhancing Stretchable Nanocomposites for Bioelectronic Devices

In a recent leap forward in bioelectronic technology, a team of researchers has unveiled a pioneering strategy that employs stretchable and conductive nanocomposites. This novel approach is critical to enhancing the performance of wearable devices, such as electronics that mimic the skin and boosting the functionality of implantable bioelectronics and soft robotics. The traditional methodologies in this domain have consistently faced challenges in amalgamating fragile electrode materials with pliable polymers, primarily due to the stark mechanical discrepancies between these elements. This has been a notable hurdle in crafting ultra-thin, flexible, conductive, efficient, and durable nanocomposites.

A notable material that has gained attention for its potential in this field is laser-induced graphene (LIG), created by subjecting polyimide (PI) to laser irradiation. LIG is celebrated for its digital patterning ability, versatile physical and chemical attributes, and applicability in crafting a range of wearable sensors. Nevertheless, the integration of LIG into functional devices has been hindered by its brittle nature and limited compatibility with specific substrates.

To surmount these challenges, the research team introduced a groundbreaking LIG-hydrogel-based nanocomposite that is ultra-thin and geared towards multifaceted use, such as on-skin sensors and implantable bioelectronics. The cornerstone of this innovation is a unique cryogenic transfer method, whereby LIG is transferred onto a hydrogel film at a cryogenic temperature of 77 Kelvin (around -196°C). This technique addresses the mechanical mismatch issue by employing the hydrogel as a medium for energy dissipation and electrical conduction, enabling seamless integration of the LIG with the hydrogel.

A significant triumph of this methodology is the dramatic improvement in the LIG's inherent stretchability. The process engenders continuously deflected cracks within the LIG, which enhances its stretchability by over fivefold. This development heralds a new era in the construction of carbon-hydrogel-based stretchable nanocomposites that are ultra-thin and exceptionally strong, setting the stage for integrated sensor systems in wearable and implantable bioelectronics.

Kaichen Xu, the study’s lead investigator, discussed the limitations of traditional LIG transfer techniques, which necessitated thicker substrates for adequate transfer, thus limiting their usability in bioelectronics. Xu and his team bypassed these obstacles through the cryogenic transfer method, utilising an ultra-thin, adhesive hydrogel made from polyvinyl alcohol, phytic acid, and honey (PPH).

The study further delves into molecular dynamics calculations, revealing an increased interfacial binding energy between the graphene and the hydrogel's crystallised water at cryogenic temperatures. This observation was supported by a peeling test, which indicated a significant rise in the peeling force at 77 Kelvin, underscoring the efficacy of the cryogenic process in enhancing the graphene-hydrogel interface's durability.

The versatility of this transfer technology was further demonstrated by the successful transfer of LIG onto various hydrogels. It was noted, however, that only adhesive hydrogels could maintain a stable mechanical binding interface when subjected to tensile strain.

The practical implications of this breakthrough are vast. The researchers have adeptly integrated multimodal sensor components into a multi-functional wearable sensor sheet tailored for on-skin in vitro monitoring. This was achieved by combining laser direct writing and the cryogenic transfer technique. The ultra-thin and biocompatible nature of the micropatterned LIG-based nanocomposites facilitates their seamless integration with living tissues. In a significant application, the team demonstrated the potential of this technology by monitoring cardiac signals in Sprague Dawley (SD) rats, highlighting the possibilities for real-time, in situ monitoring of vital biological functions.

This advancement in stretchable graphene-hydrogel interfaces represents a significant milestone in bioelectronic technology. This research paves the way for developing advanced wearable and implantable bioelectronics by addressing the longstanding challenge of mechanical mismatch in conductive nanocomposites. These devices promise to revolutionise our interaction with and monitoring of biological systems, potentially leading to breakthroughs in medical diagnostics, personalised healthcare, and human-machine interfaces.

Under the leadership of Kaichen Xu, this research presents a viable approach for creating ultra-thin, stretchable nanocomposites and lays the groundwork for future innovations in bioelectronics. The work emphasises the critical role of interdisciplinary collaboration in overcoming technical barriers and advancing technological frontiers for improving human health and well-being.
