Researchers led by the Department of Energy\u2019s Pacific Northwest National Laboratory (PNNL) have achieved a remarkable scientific feat. They have successfully created a uniform two-dimensional (2D) layer of silk protein fragments, known as fibroins, on graphene \u2014 a carbon-based material celebrated for its excellent electrical conductivity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThese results provide a reproducible method for silk protein self-assembly that is essential for designing and fabricating silk-based electronics,\u201d lead author Chenyang Shi, a postdoctoral research associate at PNNL, said in a <a href=\"https:\/\/www.pnnl.gov\/news-media\/flexible-circuits-made-silk-and-graphene-horizon\">news release<\/a>. \u201cIt\u2019s important to note that this system is nontoxic and water-based, which is crucial for biocompatibility.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The combination of silk and graphene could form highly sensitive, tunable transistors. These advanced materials are poised to greatly benefit the microelectronics industry, particularly for wearable and implantable health sensors. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The team also envisions their potential as critical components in memory transistors, or &#8220;memristors,&#8221; which are integral to neural computing networks. These memristors would enable computers to mimic the human brain&#8217;s functionality, representing a significant leap in computational technology.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A Rich History, A Bright Future<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Silk&#8217;s journey from a coveted commodity traded along the ancient Silk Road to a symbol of luxury in European markets is well-documented. Its inherent properties \u2014 elasticity, durability and strength \u2014 have led to its adoption in various advanced material applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThere&#8217;s been a lot of research using silk as a way of modulating electronic signals, but because silk proteins are naturally disordered, there\u2019s only so much control that\u2019s been possible,\u201d James De Yoreo, a Battelle Fellow at PNNL and a professor of materials science and engineering at the University of Washington, said in the news release. \u201cSo, with our experience in controlling material growth on surfaces, we thought \u2018what if we can make a better interface?\u2019\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By meticulously controlling the reaction conditions, the team was able to add individual silk fibers to a water-based system in a precise manner. Their efforts resulted in a highly organized 2D layer of protein packed in parallel \u03b2-sheets, providing the structural stability required for biological electronics. This new form of silk is ultrathin \u2014 less than half the thickness of a strand of DNA \u2014 marking it suitable for the miniaturization essential in bio-electronics.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The practical implications are vast. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis type of material lends itself to what we call field effects,\u201d added De Yoreo. \u201cThis means that it\u2019s a transistor switch that flips on or off in response to a signal. If you add, say, an antibody to it, then when a target protein binds, you cause a transistor to switch states.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Future Horizons<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The study, <a href=\"https:\/\/www.science.org\/doi\/10.1126\/sciadv.ado4142\" title=\"\">published<\/a> in Science Advances, is a pioneering step towards controlled silk layering for functional electronics. Future research will focus on enhancing the stability and conductivity of silk-integrated circuits. The team is also exploring the potential for biodegradable electronics, which could revolutionize green chemistry in electronic device manufacturing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The interdisciplinary study was co-led by PNNL materials scientist Shuai Zhang and Xiang Yang Liu of Xiamen University, with significant contributions from researchers at the University of Washington, Lawrence Berkeley National Laboratory and North Carolina State University. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As silk evolves from a fabric of the past to a material of the future, its role in creating eco-friendly, cutting-edge electronic devices could be profound, firmly intertwining the threads of history with the fabric of tomorrow\u2019s technology.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Silk, known for its ancient luxury and durability, is now set to revolutionize the future of microelectronics.
