Biomass Carbon Dots: Illuminating New Era in Antimicrobial Defense and Cancer Combat

The twenty-first century has witnessed remarkable advancements across diverse facets of human life, including significant progress in the medical field, economic growth, scientific breakthroughs, and technological advancements. Despite these strides that improved living standards, the persistent threat posed by pathogenic infections caused by bacteria, fungi, viruses, etc., remains a critical concern. The enduring emergence of new variations of these infections continues to impact lives profoundly. Cancer is another looming spectre that continues to challenge human health security. Consequently, extensive research endeavours aim to develop swift, efficient, and innocuous methods for curing and preventing these infections. This paper explores a burgeoning field in physics, focusing on recent advancements in nanomaterials, particularly in developing carbon dots (CDs). Characterized by their size, which is less than 10nm, CDs have proven exceptionally beneficial in diagnosing and treating life-threatening health issues while preserving the viability of healthy cells. Their versatility is evident in various biomedical applications, serving as bioimaging probes, intracellular drug delivery agents, and agents for bactericidal and fungicidal, as well as in cancer treatment and diagnosis. The key attributes contributing to their efficacy include ease of functionalization, biocompatibility, fluorescence, low cytotoxicity, and catalytic properties. As an innovative nanomaterial, CDs showcase tremendous potential in advancing medical diagnostics and therapeutics, offering a glimpse into a future where these tiny entities play a pivotal role in ensuring human well-being. This review focuses on the antibacterial, antifungal, antiviral, and anticancerous activities of the CDs derived from various precursors derived by biomass.

A critical review focussing on the synthesis and applications of monoclinic yttrium oxide nanophosphor

Research on monoclinic Y2O3 has been limited, not because of a lack of potential applications, but rather due to challenges associated with synthesizing phase-pure material. The limited understanding of the material and its properties has hindered researchers from further exploring this compound. Some studies suggest that the B-type polymorph of Y2O3 exhibits superior performance compared to its cubic counterpart. Additionally, there are reports indicating the existence of simple synthesis techniques that could potentially overcome the material's significant disadvantage highlighted by many researchers, namely, complex synthesis routes. To date, no comprehensive reports have summarized the key findings related to B-type Y2O3. In this effort, we aim to provide an exhaustive overview of research conducted on this polymorph. This includes an examination of diverse synthesis techniques employed by researchers, theoretical studies conducted on the material, an exploration of its luminescence properties, and an overview of various applications studied thus far. 2024 Elsevier Ltd

Emerging Nanoparticle-Based Diagnostics and Therapeutics for Cancer: Innovations and Challenges

Malignant growth is expected to surpass other significant causes of death as one of the top reasons for dismalness and mortality worldwide. According to a World Health Organization (WHO) study, this illness causes approximately between 9 and 10 million instances of deaths annually. Chemotherapy, radiation, and surgery are the three main methods of treating cancer. These methods seek to completely eradicate all cancer cells while having the fewest possible unintended impacts on healthy cell types. Owing to the lack of target selectivity, the majority of medications have substantial side effects. On the other hand, nanomaterials have transformed the identification, diagnosis, and management of cancer. Nanostructures with biomimetic properties have been grown as of late, fully intent on observing and treating the sickness. These nanostructures are expected to be consumed by growth in areas with profound disease. Furthermore, because of their extraordinary physicochemical properties, which incorporate nanoscale aspects, a more prominent surface region, explicit geometrical features, and the ability to embody different substances within or on their outside surfaces, nanostructures are remarkable nano-vehicles for conveying restorative specialists to their designated regions. This review discusses recent developments in nanostructured materials such as graphene, dendrimers, cell-penetrating peptide nanoparticles, nanoliposomes, lipid nanoparticles, magnetic nanoparticles, and nano-omics in the diagnosis and management of cancer. 2025 by the authors.

"Community Resilience to Climate Change: Integrating Sociological Perspectives"

This review article aims to present the possible ways in which communities can be resilient to climate change as seen from sociological viewpoints. Thus, it provides a systematic review of the current literature to underscore the centrality of social capital, community networks, and cultural practices in strengthening adaptive capacities in various contexts. Bangladesh coastal people and New York City are two cases in which social capital enhances the process of preparedness, response, and recovery during disasters. Cultural knowledge and traditional coping mechanisms also enhance community resilience by learning to live with the environment and innovate in the face of climate change. Implications for policy focus on the need to incorporate sociological findings into climate change adaptation, calling for the promotion of community-based adaptation and governance structures. Issues related to the scalability of resilience interventions and socio-economic inequalities are presented and future directions for research to enhance the methodological approaches and support vulnerable populations are proposed. Thus, this review aligns with the goals of community empowering and adaptive governance to highlight sociological perspectives in creating resilience to climate change impacts. 2025 Betasciencepress Publishing.

Microplastics distribution and potential health implications of food and food products

Microplastics, miniscule plastic fragments ubiquitous in the environment, pose a growing threat as they infiltrate our food chain. This review delves into the contamination of various food categories, including seafood, agricultural products, and even processed foods through packaging and processing methods. Developing reliable analytical techniques to accurately detect microplastics levels within complex food matrices is crucial to gauge the true extent of this contamination. Although the entire range of potential health effects associated with microplastic intake is not yet known, there is reason to be concerned about the risks. These include the potential for microplastics to physically hurt the gastrointestinal tract, exposure to chemicals that seep from the polymers themselves, and the potential for microplastics to act as carriers for other dangerous compounds. This analysis identifies important knowledge gaps about the long-term health effects of microplastics exposure. It highlights the urgent need for more investigation to fully assess the possible dangers connected to microplastics in the food chain. Furthermore, it is imperative that efficient mitigation measures be put in place as soon as possible to protect food safety from microplastics contamination. More cooperation is required to create more stringent laws governing the use of plastic, investigate substitute materials for manufacturing and packaging, and create effective filtering systems for the processing of food and water. Through devoted research to close knowledge gaps and the implementation of strong mitigation strategies, can make proactive efforts to safeguard public health and maintain the integrity of our food supply chain for future generations. 2024 Elsevier Inc.
