Abstract

Quantum sensing using nitrogen-vacancy (NV) centers in diamond has emerged as a powerful approach for detecting extremely weak magnetic fields with high spatial resolution and ambient operational conditions. Despite their proven sensitivity in controlled environments, the performance of NV-based sensors in biological systems remains challenged by decoherence, optical scattering, and environmental noise. This study aims to investigate the capability of diamond NV centers to detect weak magnetic fields in biologically relevant environments and to evaluate the factors influencing their performance. An experimental–computational approach was employed, combining optical detection of magnetic resonance (ODMR) measurements with simulations of spin dynamics under varying environmental conditions. Nanodiamond samples were tested across buffer solutions, cell culture media, and tissue-like environments. The results indicate that NV centers retain the ability to detect weak magnetic fields in biological settings, although sensitivity decreases due to reduced coherence time and optical contrast. Surface functionalization improves stability and partially mitigates environmental effects, enhancing overall sensor performance. These findings suggest that NV-based quantum sensors offer a promising platform for non-invasive biological magnetometry, provided that material engineering and noise mitigation strategies are optimized. This study concludes that integrating quantum sensing with biological systems is feasible and can advance applications in biomedical diagnostics and cellular imaging..

Abstract

Background. Climate change poses escalating risks to public health, particularly for communities with limited adaptive capacity and high exposure to environmental hazards. Community-based health interventions have emerged as a promising approach to enhance climate resilience by integrating local knowledge, participatory governance, and context-sensitive public health strategies. These interventions shift the focus from top-down responses to locally driven adaptation, positioning communities as active agents in managing climate-related health risks. Purpose. This study aims to examine the effectiveness of community-based health interventions in strengthening climate resilience and empowering local communities through integrated adaptation and public health strategies. The research seeks to identify key mechanisms, outcomes, and enabling conditions that support sustainable and equitable health resilience at the community level. Method. A qualitative analytical design was employed, utilizing an integrative review of peer-reviewed literature, policy documents, and selected case studies related to community-based climate-health initiatives. Data were analyzed thematically to assess intervention models, governance structures, community participation, and health outcomes. Results. The findings indicate that community-based interventions enhance adaptive capacity by improving health awareness, strengthening social capital, and fostering locally relevant adaptation practices. Programs that combine public health services, environmental management, and community engagement demonstrate greater effectiveness in reducing vulnerability to climate-related health risks. Conclusion. The study concludes that community-based health interventions represent a critical pathway for achieving climate resilience. Empowering local communities through participatory and integrated strategies not only improves health outcomes but also supports sustainable and inclusive climate adaptation efforts.
