Abstract

Biocompatible optical devices are breakthrough illumination, imaging, and biomedical sensing technologies. Despite the noteworthy developments in silk, cellulose, and hydrogel-based optics, such approaches rely on expensive precursors and intricate fabrication. Therefore, agar extracted from red algae emerges as a promising biodegradable alternative as an edible, low-cost, and renewable material. This paper overviews the state-of-the-art of agar-based optical devices. Firstly, we revisit this phycocolloid’s fundamentals and highlight its appealing mechanical, optical, and electrical characteristics. Subsequently, we summarize the available agar elements, slab waveguides, and optical fibers. Lastly, we discuss their advantages and challenges by envisaging opportunities for future developments and applications.

琼脂基光学器件的最新发展
生物兼容光学设备是一种突破性的照明、成像和生物医学传感技术。尽管蚕丝、纤维素和水凝胶光学技术的发展值得关注,但这些方法依赖于昂贵的前体和复杂的制造工艺。因此,从红藻中提取的琼脂作为一种可食用、低成本和可再生的材料,成为一种有前途的可生物降解替代品。本文概述了基于琼脂的光学器件的最新进展。首先,我们重温了这种藻胶体的基本原理,并着重介绍了其极具吸引力的机械、光学和电气特性。随后,我们总结了现有的琼脂元件、板状波导和光纤。最后,我们讨论了它们的优势和挑战,展望了未来发展和应用的机遇。
