Introduction

Effectively managing Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) threats is a paramount concern for global defense, especially when considering places with limited resources. Current training approaches frequently overlook the distinct needs of low-resource settings, relying too heavily on models from high-income nations. To build genuine resilience where it is most challenging, preparedness programs must be practical, culturally relevant, and specifically tailored to local contexts [1].

In the face of chemical threats, nanomaterials are emerging as crucial tools for both protection and cleanup. These tiny structures boast remarkable surface area and unique properties, making them highly effective for sensing, neutralizing, and decontaminating hazardous chemical agents. This signifies a move towards more efficient and less cumbersome protective gear alongside improved environmental remediation [2].

Detecting biological warfare agents quickly and accurately is vital for minimizing their impact. Significant progress is evident in using aptamer-functionalized nanomaterials for this purpose. These innovative platforms specifically bind to pathogens, enabling incredibly sensitive and rapid detection. Such capabilities are essential for early warning and response in biodefense situations [3].

Beyond specialized nanomaterial applications, emerging technologies are reshaping biosensing and diagnostics for biodefense broadly. These include miniaturized, high-throughput, and multiplexed platforms that can identify multiple biological threats simultaneously and with speed. The drive is towards point-of-care devices that deliver actionable intelligence directly in the field, accelerating critical decision-making and response times during emergencies [7].

Beyond early detection, rapid pathogen identification is transforming public health and biodefense. Next-Generation Sequencing (NGS) is a key player here, allowing for incredibly swift and precise identification of pathogens. It helps track their evolution and understand transmission dynamics. This capability is pivotal for quickly responding to biological threats, enabling a rapid shift from initial detection to informed countermeasure deployment [5].

Alongside these advancements, the development of advanced materials for personal protection against both chemical and biological warfare agents remains a continuous challenge. Innovations in materials science, particularly in composites and smart textiles, offer enhanced barrier properties, selective filtration, and even self-decontamination. These materials are evolving to provide lighter, more comfortable, and more effective protection for frontline responders and military personnel [6].

The development of antiviral therapies specifically for biodefense is another critical area. While strides have been made, challenges persist in creating broad-spectrum antivirals and rapidly deployable countermeasures for new threats. Sustained investment and innovative approaches are essential for building a strong defense against biological warfare agents [4].

Complementing this, Host-Directed Therapies (HDTs) are proving to be a promising strategy against viral infections, including those with biothreat potential. Rather than directly attacking the virus, HDTs modify the host's cellular pathways to lessen viral replication or boost immune responses. This approach could offer a broader spectrum of activity and a higher barrier to resistance, creating a vital new path for managing novel or drug-resistant biological threats [9].

Synthetic biology also provides a powerful toolkit for the rapid development of vaccines and therapeutics, particularly against emerging infectious diseases. Engineered biological systems can accelerate everything from diagnostic assay development to the production of novel vaccines and antibodies. The speed and modularity of synthetic biology are crucial when dealing with unpredictable and fast-spreading biological agents [10].

Integrating these diverse fields, Artificial Intelligence (AI) and Machine Learning (ML) are fundamentally changing our approach to chemical and biological defense. These technologies are applied across early threat detection and surveillance, accelerating countermeasure development, and optimizing logistical responses. By using AI, we can process vast data, predict attack vectors, and design more effective defenses much faster than ever before [8].

Description

Addressing Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) threats effectively requires a multi-faceted approach, starting with preparedness. It is clear that understanding the unique training needs for managing CBRNE threats in low-resource settings is crucial for global defense. A systematic review reveals that current training often misses specific local requirements, focusing too much on models from high-income countries. This highlights the necessity of tailoring preparedness programs, making them practical and culturally relevant, to truly build resilience in the most challenging environments [1].

Technological advancements are significantly enhancing our defensive capabilities against chemical agents. Nanomaterials, with their unique properties, are becoming game-changers for protecting against and cleaning up chemical threats. These tiny structures offer incredible surface area, making them highly efficient for sensing, neutralizing, and decontaminating hazardous chemical agents. This leads to a future with more effective and less cumbersome protective gear, alongside improved environmental remediation strategies [2]. In tandem, developing advanced materials for personal protection against both chemical and biological warfare agents remains a key challenge. Recent innovations in materials science focus on composites and smart textiles, which provide enhanced barrier properties, selective filtration, and even self-decontamination capabilities. These materials are evolving to offer lighter, more comfortable, and highly effective protection for frontline responders and military personnel [6].

Rapid and sensitive detection systems are absolutely critical for mitigating the impact of biological warfare agents. Research demonstrates significant progress in using aptamer-functionalized nanomaterials for this purpose. These innovative platforms specifically bind to pathogens, allowing for incredibly sensitive and rapid detection, which is vital for early warning and response in biodefense scenarios [3]. Furthermore, Next-Generation Sequencing (NGS) is fundamentally transforming public health and holds immense implications for biodefense. NGS enables incredibly rapid and precise identification of pathogens, tracking their evolution, and understanding transmission dynamics. This capability is pivotal for quickly responding to biological threats, moving from detection to informed countermeasure deployment with unprecedented speed [5]. Complementing these, emerging technologies are reshaping biosensing and diagnostics for biodefense, highlighting miniaturized, high-throughput, and multiplexed platforms. These are capable of identifying multiple biological threats simultaneously and rapidly, pushing towards point-of-care devices that deliver actionable intelligence directly in the field, thereby accelerating decision-making and response times in emergencies [7].

Beyond detection and protection, therapeutic development is advancing rapidly. Antiviral therapies specifically for biodefense have seen strides, but challenges persist in developing broad-spectrum antivirals and rapidly deployable countermeasures for emerging threats. Sustained investment and innovative approaches are thus essential to build a robust arsenal against biological warfare agents [4]. A promising new avenue is Host-Directed Therapies (HDTs) for viral infections, including those with biothreat potential. Instead of directly targeting the virus, HDTs modulate the host’s cellular pathways to reduce viral replication or boost immune responses. This could offer a broader spectrum of activity and a higher barrier to resistance, providing a critical new strategy for managing novel or drug-resistant biological threats [9]. Synthetic biology also offers a powerful toolkit for rapidly developing vaccines and therapeutics to counter biological threats, especially emerging infectious diseases. Engineered biological systems accelerate diagnostic assay development and the production of novel vaccines and antibodies. The speed and modularity inherent in synthetic biology are crucial when facing unpredictable and fast-spreading biological agents [10].

Integrating these diverse advancements, Artificial Intelligence (AI) and Machine Learning (ML) are fundamentally changing how we approach chemical and biological defense. These technologies are applied across early threat detection and surveillance, accelerating countermeasure development, and optimizing logistical responses. By leveraging AI, vast amounts of data can be processed, attack vectors predicted, and more effective defenses designed much faster than ever before. This ensures a more proactive and agile defense strategy in an evolving threat landscape [8].
