单纳米尺度物体的纳米流体操控——当前进展、挑战与未来机遇
Nanofluidic Manipulation of Single Nanometric Objects: Current Progress, Challenges, and Future Opportunities
纳米尺度物体(包括非生物和生物物体)的操控,为化学、生物学、化学与生物医学工程、材料与机械工程以及各种工业应用领域带来了突破性变革。然而,由于纳米尺度的极端微小性,无论是针对单纳米尺度物体还是分子,要实现操控的高精度、高准确性与高通量仍面临着巨大的挑战。纳米流体技术已经展示出在纳米尺度上传输离子和小分子物质的独特能力。我们认为,基于芯片的纳米流体器件因其尺度与纳米物体的尺度相当,为单纳米尺度物体和分子的高精度、高准确性与高通量操控提供了有效的策略。本文综述了当前单纳米尺度物体的纳米流体操控进展,探讨了纳米流体技术发展所面临的挑战。此外,本文还探讨了这一领域的未来机遇,强调了应对挑战的可能解决方案,并旨在促进关于纳米流控技术的讨论,从而推动该领域突破现有局限。
The manipulation of nanometric objects, encompassing both non-biological and biological objects, offers a transformative avenue for breakthroughs in diverse fields, such as chemistry, biology, chemical and biomedical engineering, materials and mechanical engineering, and various industrial applications. However, achieving accuracy, precision, and high throughput in the manipulation of nanometric objects, whether on the scale of a single nanometric entity or molecule, is a formidable challenge because of the extremely small dimensions involved. Nanofluidics has already demonstrated unique capabilities for transporting the mass of ions and small molecules at the nanoscale. We posit that chip-based nanofluidic devices provide potent strategies for the precise, accurate, and high-throughput manipulation of single nanometric entities and molecules, benefiting from their dimensions, which are comparable to those of nanometric objects. This article offers an overview of the current progress in nanofluidic manipulation of single nanometric objects. It also discusses the challenges in the development of nanofluidic manipulation technologies. Furthermore, the article explores future opportunities in the field, highlighting possible solutions to the challenges, and aims to contribute to the ongoing discourse on nanofluidic manipulation, thus propelling the field to overcome its current limitations.
