Bioinspired & Integrative Science

The Team

Aravind Kumar Jayasankar

Postdoctoral Fellow

I currently work as Research Fellow at Fermart lab. My current project involves understanding and predicting the shape deformation behavior of 3D printed bio composites during their ambient curing process. I employ a combination of experimental methods coupled with finite element analysis and machine learning to understand and optimize the mechanics and material behavior of the deformed structure. I graduated my Ph.D. at Max Planck Institute Germany, where I worked on understanding the form-functional behavior of shark and stingray cartilaginous skeleton. The cartilaginous skeleton exhibited mutually exclusive properties of stiffness and flexibility in compression and tension. I translated the biological samples into digital models to parameterize their morphology, form vs function behavior and the relationship between material and structure. My key research interests are structural mechanics of biological materials, 4D mechanisms, additive manufacturing, product design and medical technology.
With a career in science I had the opportunity to live and work in different countries and I am looking forward to exploring more. Apart from science I actively participate in meetups involving startups, trying to expose myself to new technological ideas and improve my understanding about other technological domains. In my free time, I fly drones, enjoy swimming in the sea, and explore new places, food and cultures. I am a PADI certified advanced open water scuba diver, photographer and conservationist.
Feel free to get in touch with me, I am excited to discuss everything about science, travel and photography. Personal Page

Hemant Kumar Raut

Postdoctoral Fellow

The goal of my multidisciplinary research is to apply structural designs inspired from nature to develop bio-inspired materials. In a broad range of research works (over 16 publications with 1650+ citations), I have demonstrated that bio-inspired hierarchical (micro-/nano-structure) interfaces/surfaces could exhibit multifunctional properties (highlights in Chemical and Engineering News and ScienceDaily). More specifically, in my current research, I am developing color-producing hierarchical structures that ties with my previous research on bio-inspired micro-/nano-structure arrays that could suppress optical reflections. I have also demonstrated that bristles-like hierarchical structures inspired from gecko toepads could help develop adhesive films that could be reused over 200 times. The manufacturing of these complex structures has become possible due to a distinctive nanofabrication technique (SLAN) that I had developed during my doctoral research at NUS Mechanical Engineering. In a recently concluded SUTD-MIT fellowship (2016-18), I have also added another dimension to my work. I have investigated the growth of minerals on interfaces (biomineralization) that has led to the manufacturing of a composite that exhibits unprecedented combination of strength and toughness. Such materials have diverse applications in fields ranging from biomedical to defense, which we are also studying in parallel.

Research Projects

• Fungus-like Additive Materials

  Large-scale manufacture with biological materials

  Cellulose is the most abundant and broadly distributed organic compound and industrial by-product on Earth. Yet, despite decades of extensive research, the bottom-up use of cellulose to fabricate 3D objects is still plagued with problems that restrict its practical applications: derivatives with vast polluting effects, used in combination with plastics, lack of scalability and high production cost.

  We have demonstrated the use of cellulose to sustainably manufacture/fabricate large 3D objects. Our approach diverges from the common association of cellulose with green plants and is inspired by the wall of the fungus-like oomycetes, which is reproduced introducing small amounts of chitin between cellulose fibers. The resulting fungal-like adhesive material(s) (FLAM) are strong, lightweight and inexpensive, and can be molded or processed using woodworking techniques. This material is completely ecologically sustainable as no organic solvents or synthetic plastics were used to manufacture it. It is scalable and can be reproduced anywhere without specialised facilities. FLAM is also fully biodegradable in natural conditions and outside composting facilities. The cost of FLAM is in the range of commodity plastics and 10 times lower than the cost of common filaments for 3D printing, such as PLA (polylactic acid) and ABS (Acrylonitrile Butadiene Styrene), making it not only more sustainable but also a more cost-effective substitute.

  This first large-scale additive manufacturing process with the most ubiquitous biological polymers on earth will be the catalyst for the transition to environmentally benign and circular manufacturing models, where materials are produced, used, and degraded in closed regional systems. This reproduction and manufacturing with the material composition found in the oomycete wall, namely unmodified cellulose, small amounts of chitosan –the second most abundant organic molecule on earth — and low concentrated acetic acid, is probably one of the most successful technological achievements in the field of bioinspired materials.

• Shrilk family of materials

  Man-made Natural Materials

  Plastics production has increased from 0.5 to 380 million tons per year since 1950. The increasing use of plastics, which in most cases are prepared by polymerization of monomers derived from a nonrenewable source, creates major waste management and environmental problems. Most of the plastic produced is used to make disposable items or other short-lived products that are discarded within a year of manufacture. These objects account for approximately 30 percent of the waste we generate, which accumulates in landfills or contaminates large areas of marine habitats – from remote shorelines and heavily populated coastlines to areas of the deep sea that were previously thought to be virtually inaccessible. These factors highlight the unsustainability of the current use of plastics, which is driving a growing interest in biomaterials that are fully biodegradable and recyclable.

  At the Fermart lab we are developing the next generation of materials for sustainable development. Our first version of “Shrilk”, based on the chemistry and molecular design of the insect cuticle, is transparent, biodegradable, and has an ultimate strength in the same range as aluminum alloys, but at half their density. It is made of silk proteins and waste material from the fishing industry (i.e. chitin). Seafood processing factories generate over 250 billion tons of chitin biopolymer that is typically dumped back into the ocean, negatively affecting coastal ecosystems.

  Shrilk represents a groundbreaking approach to sustainable development. It is based on the association of natural components and their molecular design as a sole entity. We demonstrated how structural natural materials with engineering relevance, are only achievable by controlling both characteristics and their relation. This approach, linking together manufacture, biological design, and biomolecules, has started a complete new approach to sustainable and bioinspired materials.

  Shrilk is considered one of the most important advancements for sustainable development in the last decade. It has been reviewed by the most prominent media outlets around the world, and has been referred as “one of the materials that will change the future of manufacturing” (Scientific American), as a “Supermaterial” (National Geographic) and as “the material that will save the world” (BBC).

• Biomaterials for Medicine

  Biomaterials for tissue engineering and biomedicine

  Biomaterials are used in medical devices or in contact with biological systems. Biomaterials as a field has seen steady growth over its approximately half century of existence and is highly multidisciplinary, as it merges medicine, biology, chemistry, materials science and engineering. While biomaterials were traditionally designed to be inert in a biological environment, new biomaterials capable of triggering specific biological responses at the tissue/material interface have been reaching clinical application.
