Whitesides (2006) outlined microfluidics applications in continuous flow chemistry and chemical synthesis, impacting over 62,306 works. Duffy et al. (1998) demonstrated rapid prototyping of PDMS microfluidic systems in less than 24 hours, facilitating high-throughput screening in drug discovery and emulsion generation for industrial processes. Unger et al. (2000) developed monolithic microfabricated valves and pumps via multilayer soft lithography, enabling complex microreactor technologies for scalable biomedical applications.
Reading Guide
Where to Start
"The origins and the future of microfluidics" by George M. Whitesides (2006) provides a foundational overview of microfluidics history, principles, and applications, making it ideal for newcomers before diving into technical fabrication or application papers.
Key Papers Explained
Whitesides (2006) establishes microfluidics foundations, which Duffy et al. (1998) build on with rapid PDMS prototyping (5214 citations), and Xia and Whitesides (1998) expand via soft lithography (4550 citations). Unger et al. (2000) advance this to multilayer valves and pumps (3967 citations), while Stroock et al. (2002) address mixing limitations (3320 citations). Macosko et al. (2015) and Klein et al. (2015) apply these to single-cell analysis with droplet techniques (7531 and 3548 citations).

Frequently Asked Questions
What is droplet microfluidics?
Droplet microfluidics involves generating and manipulating discrete droplets in microchannels for applications like high-throughput screening and single-cell analysis. Macosko et al. (2015) used nanoliter droplets for parallel genome-wide expression profiling of individual cells. This technique supports continuous flow chemistry and emulsion generation across 62,306 works.
How does soft lithography enable microfluidic fabrication?
Soft lithography uses replica molding of elastomeric materials like PDMS to create micro- and nanostructures without photolithography. Xia and Whitesides (1998) described it as a low-cost method for microfabrication, cited 4550 times. Duffy et al. (1998) applied it to prototype microfluidic systems with channels over 20 μm wide in less than 24 hours.
What are applications of microfluidics in single-cell analysis?
Microfluidics supports single-cell transcriptomics through droplet barcoding and nanoliter droplet profiling. Klein et al. (2015) applied droplet barcoding to embryonic stem cells, earning 3548 citations. Macosko et al. (2015) achieved highly parallel expression profiling, advancing biomedical applications.
How do chaotic mixers function in microchannels?
Chaotic mixers induce mixing in laminar microchannel flows via passive surface patterns that generate transverse velocity components. Stroock et al. (2002) presented such a mixer, cited 3320 times, addressing slow molecular diffusion. This improves efficiency in continuous flow chemistry and chemical synthesis.
