“…Table 2 summarises the optical imaging methods commonly used for visualization of fluid distribution, two-phase flow, solute transport, particle dynamic transport and reactive transport in micromodels. They include camera, microscope-camera, photoluminescent volumetric method, confocal microscopy, Raman microscopy, and micro particle image velocimetry (µPIV) [ 18 , 73 , 112 , 114 , 115 , 116 , 117 , 139 , 149 , 150 , 151 , 152 , 153 , 154 , 155 , 156 , 157 ]. Generally, these methods are low cost and probably represent the easiest option for imaging micromodels [ 5 ].…”

“…Singh et al [ 139 ] used confocal Raman spectroscopy to conduct in-situ mineral characterization of a 500 µm-thick section of a real rock sample before and after embedding in a PDMS microchannel. Poonoosamy et al [ 153 ] integrated a microfluidic chip with high-resolution imaging including optical microscopy and Raman spectroscopy for in-situ, non-destructive and real-time monitoring of chemical and transport processes. X-ray µCT imaging has recently made it feasible to perform in-situ contact angle measurement feasible [ 215 , 223 , 224 , 225 , 226 , 227 , 228 ].…”

Understanding transport phenomena and governing mechanisms of different physical and chemical processes in porous media has been a critical research area for decades. Correlating fluid flow behaviour at the micro-scale with macro-scale parameters, such as relative permeability and capillary pressure, is key to understanding the processes governing subsurface systems, and this in turn allows us to improve the accuracy of modelling and simulations of transport phenomena at a large scale. Over the last two decades, there have been significant developments in our understanding of pore-scale processes and modelling of complex underground systems. Microfluidic devices (micromodels) and imaging techniques, as facilitators to link experimental observations to simulation, have greatly contributed to these achievements. Although several reviews exist covering separately advances in one of these two areas, we present here a detailed review integrating recent advances and applications in both micromodels and imaging techniques. This includes a comprehensive analysis of critical aspects of fabrication techniques of micromodels, and the most recent advances such as embedding fibre optic sensors in micromodels for research applications. To complete the analysis of visualization techniques, we have thoroughly reviewed the most applicable imaging techniques in the area of geoscience and geo-energy. Moreover, the integration of microfluidic devices and imaging techniques was highlighted as appropriate. In this review, we focus particularly on four prominent yet very wide application areas, namely “fluid flow in porous media”, “flow in heterogeneous rocks and fractures”, “reactive transport, solute and colloid transport”, and finally “porous media characterization”. In summary, this review provides an in-depth analysis of micromodels and imaging techniques that can help to guide future research in the in-situ visualization of fluid flow in porous media.

“…For example, particle image velocimetry has highlighted internal fluid eddies within droplets trapped by capillary forces whose large scale impact is not included in multiphase Darcy's law (Kazemifar et al, 2016;Roman et al, 2016Roman et al, , 2020Zarikos et al, 2018). Microfluidics also led to substantial advancements in the understanding of reactive systems as the most recent microchips involve reactive materials to investigate dissolution and precipitation of solid minerals in fractured porous media (Zhang et al, 2013;Song et al, 2014;Porter et al, 2015;Osselin et al, 2016;Soulaine et al, 2017Soulaine et al, , 2018Yoon et al, 2019;Agrawal et al, 2020;Poonoosamy et al, 2020;Yun et al, 2020). In just a few decades, microfluidics has become an indispensable tool in geosciences to decipher the complex mechanisms that occur in porous systems and the discipline keeps improving.…”

“…Although it is often restricted to small micro-CT images (<300 3 voxels) or to single-phase flow due to high computing cost, computational microfluidics is also well-suited to investigate pore-to-pore physics (Ferrari and Lunati, 2014;Pavuluri et al, 2020) with the objective of improving upscaling techniques (e.g., pore entry pressure for pore network modeling). A major asset of microfluidics is the ability to design well-controlled experiments and obtain high-resolution measurements-both in space and time-of the velocity fields (Roman et al, 2016), phase distribution, film thickness (Roman et al, 2017), aqueous species concentrations (Chang et al, 2017), and mapping in mineral changes (Poonoosamy et al, 2020). Microfluidics is inestimable to verify the numerical models using direct comparison with microfluidic experiments (Willingham et al, 2008;Yoon et al, 2012;Chapman et al, 2013;Oostrom et al, 2016;Roman et al, 2017;Soulaine et al, 2018).…”

Computational microfluidics for geosciences is the third leg of the scientific strategy that includes microfluidic experiments and high-resolution imaging for deciphering coupled processes in geological porous media. This modeling approach solves the fundamental equations of continuum mechanics in the exact geometry of porous materials. Computational microfluidics intends to complement and augment laboratory experiments. Although the field is still in its infancy, the recent progress in modeling multiphase flow and reactive transport at the pore-scale has shed new light on the coupled mechanisms occurring in geological porous media already. In this paper, we review the state-of-the-art computational microfluidics for geosciences, the open challenges, and the future trends.

with advanced functions, [6] can be attributed to two aspects. 1) The exquisite control and manipulation abilities of fluids at a microscale have reached a new height as droplet microfluidic technology is leaping forward. The precisely tunable interface characteristics of emulsion templates, determined by the optimization of fluids composition and interfacial complexity, contribute to the inherent interface properties of MPRs. [7][8][9][10] 2) The introduction of advanced materials expands the interface characteristics of the MPRs. Considerable natural polymers, synthetic polymers, and stimuli-responsive biomaterials have been employed continuously with the development of materials science. As a result, a series of performances possessed by the materials can significantly improve the inherent interface characteristics of the MPRs under a combination of the mentioned advanced materials. [11][12][13][14][15][16] Overall, researchers have stressed the improvement of the development process of interface characteristics and functions (such as substance encapsulation and controlled release) by providing novel technical innovations in every aspect to support biomedical clinical applications related to cells and drugs. Recently, the types, preparation methods, and biomedical applications of MPRs have been systematically presented in several excellent reviews. [3][4][5][8][9][10][17][18][19][20] The thermodynamic properties of liquid-liquid droplet reactors have been analyzed more specifically in some reviews. [7,17] However, the origin of interface characteristics of MPRs, as well as the function and cuttingedge cell-and drug-related biomedical applications determined by the interface characteristics, are deficient in a systematic summary. This review highlights that different emulsion templates endow the inherent interface characteristics of MPRs. Besides, the methods of converting emulsion templates into MPRs are summarized by introducing specific functional biomaterials, followed by the flexible and adjustable interface characteristics expanded by the mentioned materials. Moreover, the biomedical applications related to cells and drugs are analyzed based on the mentioned unique interface characteristics of the MPRs. Furthermore, the existing challenges regarding the current status are presented, and the subsequent development of the MPRs is illustrated from various perspectives (Scheme 1).
