The growing demand for sustainable, high-performance materials has accelerated research into natural polymer–nanoclay composites as alternatives to petroleum-based plastics and conventional biomaterials. Natural polymers such as cellulose, chitosan, and alginate offer biodegradability, biocompatibility, and chemical functionality, but their standalone use is often limited by inadequate mechanical strength, thermal stability, and barrier performance. Incorporation of naturally occurring nanoclays, including montmorillonite and halloysite nanotubes, overcomes these limitations by providing structural reinforcement, enhanced barrier properties, and tunable bioactive delivery capabilities. This review critically examines recent advances in the design, interfacial chemistry, and multifunctional performance of natural polymer–nanoclay composites, with particular emphasis on stimuli-responsive behavior and bioactive loading strategies. Mechanisms governing pH-, temperature-, moisture-, ionic-, and light-responsive responses are discussed in relation to controlled release and adaptive functionality. A comparative perspective highlights how shared material principles are tailored to meet the distinct performance and regulatory requirements of food packaging and biomedical applications, including shelf-life extension, antimicrobial activity, wound healing, and drug delivery. Fabrication approaches, scale-up challenges, and safety and regulatory considerations relevant to both sectors are also addressed. Despite substantial progress, challenges remain in achieving scalable manufacturing, ensuring long-term safety, and minimizing environmental persistence of nanoclay components. Overall, natural polymer–nanoclay composites represent a promising class of multifunctional, sustainable materials capable of bridging food safety and biomedical innovation through rational material design.

This review explores the multifaceted relationship among infant heart development, early attachment experiences, and lifelong cardiovascular risks, shaped by genetic, environmental, and technological factors. The primary objective is to synthesise current global research on how congenital heart disease (CHD), parent-infant bonding, and early biological regulation interact to influence long-term cardiac health. Infant cardiac maturation depends on precise genetic programming, but it is susceptible to prenatal conditions, epigenetic modifications, perinatal inflammation, and preterm birth. Beyond structural development, early attachment plays a significant role in modulating stress physiology and autonomic balance, both of which have lasting impacts on cardiovascular function. Secure attachment is increasingly recognised as a protective factor that can buffer the effects of early biological vulnerabilities associated with cardiac disease. At a global level, CHD remains one of the most prevalent congenital anomalies, and advancing neonatal care has transformed survival outcomes. However, this improved survival has highlighted the growing burden of heart failure and other chronic complications later in life. Current clinical trials across continents are examining new biomarkers, early detection techniques, and interventions that target both cardiac repair and developmental adaptation. Parallel to these medical advances, digital health innovations are dramatically reshaping paediatric cardiology. Internet of Things (IoT)-based technologies—such as biosensing wearables, wireless monitors, and cloud-supported data analytics—are creating new possibilities for continuous monitoring and predictive modelling of infant cardiac health. These tools enable early detection of abnormalities, assist in personalised care planning, and may help forecast long-term heart failure risks by integrating physiological, behavioural, and environmental data. This interdisciplinary review calls for closer collaboration among cardiologists, developmental scientists, and data engineers to develop equitable, ethically responsible predictive systems. By linking traditional clinical understanding with emerging digital frameworks, it emphasises a holistic perspective on the prevention and management of cardiovascular disease from infancy through adulthood.
