In this review, we explore two of the most used designs for droplet generation: T-junction and flow focusing. First, we discuss how it is possible to predict droplet size in microfluidics. Then, we introduce the results we have obtained for...

In microfluidics, it is essential that devices have a stable and well-characterized surface, especially when used for biomedical applications. We generally classify coatings between two groups: covalent and adsorptive. In this review, we will present the most relevant coatings used...

The droplet size is strongly dependent on the continuous phase flow rate and the sizes of both the dispensing nozzle and the flow-focusing orifice. In this review, we will report the results of Rahimi’s publication on the effect of the...

Platforms based on microfabrication and microfluidics have been successfully utilized in a variety of applications such as drug discovery, polymer chain reaction (PCR), single-cell analysis or crystallization proteins to name a few. For all of these applications, producing droplets at...

The step emulsification is a variant of the droplet generation technique called co-flow. This new technique is based on the instability of a two-phase liquid wire triggered by an abrupt change in the flow confinement (Figure 1). It is more...

A widely used microfluidics approach to create emulsions is based on the production of droplets of one fluid dispersed in another immiscible fluid (mainly oils), at frequencies of the order of one to thousands of droplets per second. Droplet-based microfluidics...

In this review, we will discuss the different coating methods to generate droplets in a microfluidic device. There are mainly two types of coating: hydrophobic and hydrophilic. Regardless of the type of coating to be applied, two parameters must be...
