Nature’s light manipulation strategies—in particular those at the origin of bright iridescent colors—have fascinated humans for centuries. In recent decades, insights into the fundamental concepts and physics underlying biological light-matter interactions have enabled a cascade of attempts to copy nature’s optical strategies in synthetic structurally colored materials. However, despite rapid advances in bioinspired materials that emulate and exceed nature’s light manipulation abilities, we tend to create these materials via methods that have little in common with the processes used by biology. In this review, we compare the processes that enable the formation of biological photonic structures with the procedures employed by scientists and engineers to fabricate biologically inspired photonic materials. This comparison allows us to reflect upon the broader strategies employed in synthetic processes and to identify biological strategies which, if incorporated into the human palette of fabrication approaches, could significantly advance our abilities to control material structure in three dimensions across all relevant length scales.

Introduction: Pharmaceutical formulation scientists are currently developing new materials and formulations which vividly include Nutraceuticals. "Nutraceutical" is a substance that is considered a food or part of a food processed as pharmaceutical, which provides medical or health benefits, encompassing prevention and treatment of diseases. Materials and Methods: Under this research Nutraceutical Product Mixture was prepared using seeds of Cucumis melo, Punica granatum and Linum usitatissimum. Individually these three seeds are reported to contain rich nutrients along with antioxidants, probiotic soluble fibres and thus the mixture of three increased this potential. Individual seed and the mixture was evaluated by In-vitro and In-vivo methods for Nutraceutical Potential. Results: Proximate analysis of the mixture showed rich nutrient content and provided good combination of nutrients. Individual seed powder as well as mixture was tested for prebiotic potential using lactobacilli culture, which showed positive results. Each seed powder as well as mixture was tested for anti oxidant potential using DPPH free radical scavenging assay, with promising results. It's in-vivo effect was studied using Wistar albino rat as animal model. This study involved haemogram and lipid profile determination which showed certain promising results. The powder mixture was developed into two products namely capsule and health drink powder formula. Conclusion: The nutraceutical powder mixture of seeds of Cucumis melo, Punica granatum and Linum usitatissimum could be a promising product with antioxidant, prebiotic and nutraceutical potential for diabetic and cardiac patients where oxidative stress is a major underlying cause.
