核酸的纳米工程催生了令人兴奋的高端生物成像分子技术。可预测的碱基配对,高可编程性,以及用于获取不同长度和高纯度的核酸的卓越的新的化学和生物方法,再加上用于设计它们的计算工具,使得基于核酸的纳米设备的创造成为可能。鉴于它们的生物起源,这种合成设备具有与生物世界对接的巨大能力,这种能力是几种基于核酸的技术的核心,这些技术正在生物系统中找到应用。我们讨论了这些不同的应用,并强调了核酸支架在物理化学性质方面为这些环境带来的优势。随着我们设计这种多功能支架的能力增加,它在结构、细胞和生物生物学中的应用显然准备大量扩大。
The nanoscale engineering of nucleic acids has led to exciting molecular technologies for high-end biological imaging. The predictable base pairing, high programmability, and superior new chemical and biological methods used to access nucleic acids with diverse lengths and in high purity, coupled with computational tools for their design, have allowed the creation of a stunning diversity of nucleic acid--based nanodevices. Given their biological origin, such synthetic devices have a tremendous capacity to interface with the biological world, and this capacity lies at the heart of several nucleic acid--based technologies that are finding applications in biological systems. We discuss these diverse applications and emphasize the advantage, in terms of physicochemical properties, that the nucleic acid scaffold brings to these contexts. As our ability to engineer this versatile scaffold increases, its applications in structural, cellular, and organismal biology are clearly poised to massively expand.
