“…Mahapatra et al, focused on extracting natural dyes from inedible plant sources, specifically the seeds of Bixa orellana (kumkum), the pericarp of Mallotus phillipensis (kamala) fruits, and ripe fruits of Basella alba (Malabar spinach) [241]. A comparative analysis was conducted to evaluate the efficacy of these extracts as dye sensitizers for solar cells.…”

This review explores the extensive applications of plants in areas of biomimetics and bioinspiration, highlighting their role in developing sustainable solutions across various fields such as medicine, materials science, and environmental technology. Plants not only serve essential ecological functions but also provide a rich source of inspiration for innovations in green nanotechnology, biomedicine, and architecture. In the past decade, the focus has shifted towards utilizing plant-based and vegetal waste materials in creating eco-friendly and cost-effective materials with remarkable properties. These materials are employed in making advancements in drug delivery, environmental remediation, and the production of renewable energy. Specifically, the review discusses the use of (nano)bionic plants capable of detecting explosives and environmental contaminants, underscoring their potential in improving quality of life and even in lifesaving applications. The work also refers to the architectural inspirations drawn from the plant world to develop novel design concepts that are both functional and aesthetic. It elaborates on how engineered plants and vegetal waste have been transformed into value-added materials through innovative applications, especially highlighting their roles in wastewater treatment and as electronic components. Moreover, the integration of plants in the synthesis of biocompatible materials for medical applications such as tissue engineering scaffolds and artificial muscles demonstrates their versatility and capacity to replace more traditional synthetic materials, aligning with global sustainability goals. This paper provides a comprehensive overview of the current and potential uses of living plants in technological advancements, advocating for a deeper exploration of vegetal materials to address pressing environmental and technological challenges.

Transition metal chalcogenides(TMC) have been studied for their potential applications in optoelectronic devices such as light emitting diodes, solar cells, photodetectors, field effect transistors etc. Their unique structural, versatile electronic and optical properties, non-toxic chemical nature and abundance are some of the properties that have attracted tremendous attention of researchers. In this study, optimized junctions formed between zirconium sulphide(ZrS2) and Copper zinc tin sulphide(CZTS), Cupper indium sulphide(CIS), Cupper indium selenide(CISe) and Cadmium telluride(CdTe) absorber layers have been explored and compared using the Solar Cell Capacitor Simulator(SCAPS) for photovoltaic applications. The impact of operating temperature, illumination intensity, series and shunt resistances on cell performance has been discussed in details. Comparative study concluded that the Al-ZnO/ZrS2/CZTS structure presents the best efficiency of 9.72% at room temperature. Other performance parameters obtained are 25.16mA/cm2(Jsc), 0.61(Voc) and 68.86%(FF). External quantum efficiency(EQE) response has also been examined under AM1.5 spectrum for different device model. The simulation results suggest that n-ZrS2 can be used as an excellent buffer layer to fabricate environmental friendly and non-toxic solar cells.

“…Therefore, the shelf life of certain plants and crops should be determined to maintain their quality, nutritional content, and plant tissue integrity. One application of chlorophyll is to replace synthetic dyes due to their toxicity, cost and complexity of synthesis and filtration [10][11][12]. Studies have also demonstrated that synthetic dyes have neurological, behavioral, and allergic effects such as sleep disorders, irritability, aggressiveness, and hyperactivity [4,5].…”

“…Studies have also demonstrated that synthetic dyes have neurological, behavioral, and allergic effects such as sleep disorders, irritability, aggressiveness, and hyperactivity [4,5]. Whereas natural dyes based on plant chlorophyll are inexpensive, biocompatible, biodegradable, sustainable, and have a simple extraction process [10,11], but the shelf life is still of concern.…”

This study aimed to assess the optimal conditions for the extraction of chlorophyll and the stability of chlorophyll with postharvest storage period in Moringa Oleifera leaves harvested in 3 different years for its preservation and lifespan. For this purpose, chlorophylls a (Chla) and b (Chlb) were extracted from the leaves using acetone, methanol, N, N-dimethylformamide (DMF), and the ‘green’ solvent (ethanol). In addition, the chlorophylls were extracted under various conditions, including temperatures (4, 25, and 45 °C), and times (10, 30, and 60 min) from dry leaves that were harvested in different years (2020, 2021, and 2022). The results showed that the Chla content extracted exceeded that of Chlb in the four solvents in all temperatures and extraction times, except for acetone and ethanol extracts under 45 °C at 30 and 60-min extraction times in samples harvested in 2022. An increase in extraction time and temperature resulted in higher chlorophyll content. Overall chlorophyll content decreased with the increasing postharvest storage period, particularly in methanol and ethanol extracts. The Chlorophyll Stability Index showed that chlorophyll is stable in moringa, such that the chlorophyll content obtained in a 2-year postharvest storage period samples was also found to be high. In general, the chlorophyll obtained from this study was found to be compatible with what is used in the industrial market. This suggests that the chlorophyll from moringa is stable and can be considered a major source of chlorophyll.
