(Press-News.org) A new scientific review highlights how emerging biochar-based nanomaterials could play a powerful role in tackling global challenges ranging from climate change to healthcare innovation. Researchers report that nanobiochar and biochar nanocomposites, advanced forms of carbon-rich materials derived from biomass, are showing promise across fields including renewable energy storage, sustainable construction, agriculture, and even medicine.
Biochar itself is produced by heating plant-based waste such as crop residues or forestry byproducts in low-oxygen conditions. When engineered at the nanoscale or combined with other materials, its chemical reactivity, surface area, and electrical properties increase dramatically, enabling entirely new applications.
The authors explain that these materials may help address some of the most pressing sustainability issues of our time. Because biochar is produced from waste biomass, it offers a renewable and potentially low-cost platform for designing functional materials while also supporting carbon capture strategies.
“Nanobiochar and its composites offer a rare combination of environmental sustainability and technological versatility,” said the study’s lead researchers. “With further development, these materials could support cleaner energy systems, improved health technologies, and more resilient infrastructure.”
One of the most exciting opportunities lies in energy storage. Biochar-derived nanomaterials can serve as electrodes in batteries and supercapacitors, devices essential for electric vehicles and renewable energy systems. Their porous structure and abundant surface functional groups allow efficient ion transport and improved stability, which could reduce dependence on expensive fossil-derived carbon materials.
The review also outlines potential biomedical applications. Biochar nanocomposites can be engineered to carry drugs, fight microbial infections, or support wound healing. Their high surface area enables them to load and release therapeutic compounds in a controlled way, which may help reduce side effects of conventional treatments. Some studies suggest they could even be used in cancer therapies by enhancing targeted drug delivery or altering tumor environments.
Beyond medicine and energy, the materials may also support sustainable construction and climate-smart agriculture. Biochar-based composites could strengthen building materials while storing carbon, or improve soil quality by enhancing water retention and plant growth. These multifunctional roles make the technology particularly attractive for advancing circular economy approaches.
However, the researchers caution that further work is needed before widespread adoption. Questions remain about long-term environmental impacts, biocompatibility, and the scalability of production methods. Understanding how these materials interact with living systems and ecosystems will be essential for safe implementation.
Despite these uncertainties, global research interest is growing rapidly. The authors note a sharp rise in international collaborations and publications in the field over the past decade, signaling increasing recognition of biochar nanomaterials as a frontier technology for sustainable development.
The review concludes that interdisciplinary collaboration among environmental scientists, engineers, medical researchers, and industry partners will be crucial to fully realize the potential of these materials.
As nations seek solutions that combine environmental responsibility with technological innovation, nanobiochar and biochar nanocomposites may offer a pathway toward a more resource-efficient and low-carbon future.

New ‘scimitar-crested’ Spinosaurus species discovered in the central Sahara
2026-02-19
A new paper published in Science describes the discovery of Spinosaurus mirabilis, a new spinosaurid species found in Niger. A 20-person team led by Paul Sereno, PhD, Professor of Organismal Biology and Anatomy at the University of Chicago, unearthed the find at a remote locale in the central Sahara, adding important new fossil finds to the closing chapter of spinosaurid evolution.
Eye-catching anatomy
The scimitar-shaped crest of S. mirabilis was so large and unexpected that the paleontologists initially didn’t recognize it for what it was when they plucked it and some jaw fragments from the desert surface in November 2019. Returning with a larger team in 2022 and finding two ...
“Cyborg” pancreatic organoids can monitor the maturation of islet cells
2026-02-19
Qiang Li and colleagues have created “cyborg” pancreatic organoids that combine stretchy miniature electronics with stem cell-derived pancreatic islets, using the implanted electronics to monitor electrical activity related to glucose regulation in maturing α and β cells. Islet α and β cells secrete glucagon and insulin hormones, in response to electrical changes in the cell membrane. The researchers also used the electronics to stimulate the cells to enhance their glucose responsiveness and show how that responsiveness changes as the cells mature, how it is affected by different chemical compounds and circadian ...
Technique to extract concepts from AI models can help steer and monitor model outputs
2026-02-19
AI models have their own internal representations of knowledge or concepts that are often difficult to discern, even as they are critical to the models’ output. For instance, knowing more about a model’s representation of a concept would help explain why an AI model might “hallucinate” information, or why certain prompts can trick it into responses that dodge its built-in safeguards. Daniel Beaglehole and colleagues now introduce a robust method to extract these representations of concepts, which works across several large-scale language, reasoning, and vision AI models. Their technique uses ...

Crested Spinosaurus fossil was aquatic, but lived 1,000 kilometers from the Tethys Sea
2026-02-19
A new Spinosaurus species uncovered in northern Niger by Paul Sereno and colleagues appears to have been a wading predator of fish like its close relatives, but it lived as many as 1,000 kilometers inland from the Tethys Sea. The fossil find may represent a third phase of evolution for this group of massive, fish-eating dinosaurs, according to Sereno et al. The new species Spinosaurus mirabilis, uncovered in the central Sahara near Sirig Taghat (“no water, no goat” in Tamasheq, the local Berber language), lived with long-necked dinosaurs in a riparian habitat 100-95 million years ago. Sereno et al. suggest there were ...
MULTI-evolve: Rapid evolution of complex multi-mutant proteins
2026-02-19
The search space for protein engineering grows exponentially with complexity. A protein of just 100 amino acids has 20^100 possible variants—more combinations than atoms in the observable universe. Traditional engineering methods might test hundreds of variants but limit exploration to narrow regions of the sequence space. Recent machine learning approaches enable broader searches through computational screening; however, these approaches still require tens of thousands of measurements or 5-10 iterative rounds.
With the advent of these foundational protein models, the bottleneck for protein engineering swings back ...
