WEBINAR: Transforming your crystallization process (Recording available)

Screening crystallization parameters for targeted particle size distribution might be challenging and time-consuming.

Join this webinar to discover how Secoya’s Crystallization Technology transforms the process with spontaneous nucleation, making it faster and more efficient. During this LIVE session, the setup of the instrument will be shown for both cooling and antisolvent crystallization. At the end of this webinar, Bart Rimez our technology lead will explain the overall philosophy of Secoya.

Book your seat and learn how the SCT technology can be extrapolated to other molecules, how to obtain the required particle size distribution with the setup of experimental designs and how to upscale it using the SCT-PILOT unit.

PUBLICATION: Continuous Microfluidic Antisolvent Crystallization as a Bottom-Up Solution for the Development of Long-Acting Injectable Formulations

Nandi, S. et al. Continuous Microfluidic Antisolvent Crystallization as a Bottom-Up Solution for the Development of Long-Acting Injectable Formulations. Pharmaceutics 2024, 16, 376.


A bottom-up approach was investigated to produce long-acting injectable (LAI) suspension-based formulations to overcome specific limitations of top-down manufacturing methods by tailoring drug characteristics while making the methods more sustainable and cost-efficient. A Secoya microfluidic crystallization technology-based continuous liquid antisolvent crystallization (SCT-CLASC) process was optimized and afterwards compared to an earlier developed microchannel reactor-based continuous liquid antisolvent crystallization (MCR-CLASC) setup, using itraconazole (ITZ) as the model drug. After operating parameter optimization and downstream processing (i.e., concentrating the suspensions), stable micro suspensions were generated with a final solid loading of 300 mg ITZ/g suspension. The optimized post-precipitation feed suspension consisted of 40 mg ITZ/g suspension with a drug-to-excipient ratio of 53:1. Compared to the MCR-CLASC setup, where the post-precipitation feed suspensions contained 10 mg ITZ/g suspension and had a drug-to-excipient ratio of 2:1, a higher drug concentration and lower excipient use were successfully achieved to produce LAI microsuspensions using the SCT-CLASC setup. To ensure stability during drug crystallization and storage, the suspensions’ quality was monitored for particle size distribution (PSD), solid-state form, and particle morphology. The PSD of the ITZ crystals in suspension was maintained within the target range of 1–10  m, while the crystals displayed an elongated plate-shaped morphology and the solid state was confirmed to be form I, which is the most thermodynamically stable form of ITZ. In conclusion, this work lays the foundation for the SCT-CLASC process as an energy-efficient, robust, and reproducible bottom-up approach for the manufacture of LAI microsuspensions using ITZ at an industrial scale.

The precise manipulation, quick cultivation, and delicate detection of yeast and bacteria are crucial in microbiology and biomedicine for behavior monitoring, identification of phenotypes, physiological assessment, and molecular analysis.

Microfluidic droplets have proven to be an effective method for encapsulating yeast and bacteria in highly monodisperse droplets for high-throughput screening and analysis of their phenotypes, subcellular structures, genes, and metabolites.This application note details the encapsulation of the yeast strain S. cerevisiae CEN.PK 113-7D and the bacterial strain L. cremorsi MG1363_GFP in double emulsions of 42 µm size using the Cell Encapsulation Platform, resulting in Microencapsulation of Bacteria and Yeast.

Single crystal formation in core-shell capsules (ChemComm Oct.23)

Imagine, that you can easily produce solid microcapsules acting as independent crystallization vessels for both small and macromolecular molecules. Even more, imagine their remarkable stability allows you to handle those microcapsules and transport them without any limitations or constraints.

This is exactly what has been demonstrated by our team in this new publication entitled: “Single crystal formation in core-shell capsules” (ChemComm Oct.23). A unique process made possible only with Secoya’s Raydrop® innovative device.

BREAKING NEWS: Secoya Technologies and ULB achieved a patent milestone in India.

 This momentous achievement allows Secoya Technologies to explore and expand into new markets.

NEW Application Note: A quick and efficient double emulsion generation method for flow cytometry droplet sorting

In this paper, we describe the encapsulation of a fluorescent strain of Escherichia coli bacteria in w/o/w double emulsions and flow cytometry droplet sorting using a flow cytometry cell sorter (also commonly known as FACS). The Secoya’s RayDrop platform (including the RayDrop® device and distributed by Fluigent) allows the bacteria to be compartmentalized within a protective shell and ensures compatibility with the sorting device. The platform generates double emulsions in one step, scaling the production of common two-step double emulsion generation methods by up to ten times. Several hundred microliters of emulsions can be produced in 30 minutes, and multiple conditions can be tested within a single day, compared to a week with traditional methods. In addition, the platform integrates fluidic, pneumatic, and optic solutions, and does not require complex fabrication steps nor surface treatment. This application note was written in collaboration with Delphine Lestrade (head of the flow cytometry platform at Toulouse White Biotechnology, TWB) and Sophie Lajus (researcher at the Toulouse Biotechnology Institute, TBI)

WEBINAR: Upscaling of the crystallization process towards a full continuous crystal production

About this Webinar:

During this webinar, Bart Rimez our expert in Crystallization, demonstrated how the Secoya Crystallization Technology (SCT) process can be seamlessly scaled up from laboratory to production scale by tightly controlling various parameters.

At the laboratory scale, a set of parameters is identified and enables the production of the desired particle sizes and distributions. This same set of parameters can then be directly transferred to pilot-scale or production-scale processes, thus providing a reliable and efficient means of scaling up the SCT process.

About the Secoya Crystallization Technology:


Unlike any alternative process, the Secoya crystallization technology is based on the precise control of spontaneous nucleation through the use of millifluidic tubular reactors upon cooling and different antisolvent addition possibilities. Using such capillaries, any parameter influencing the nucleation is ideally optimized and controlled.

Secoya’s crystallization technology is unique, enabling crystallization of molecules in a single process step avoiding difficult work-up when performed with conventional batch systems.


By presenting five various possibilities for microcapsules production (Chitosan, PLGA, Polymethacrylate resin, Alginate, Agarose) using the double emulsion Raydrop®  integrative platform,  this white paper outlines the versatility of Secoya encapsulation technology.

The SCT approach to crystallization

In a White Paper we described earlier what the advantages of the use of Secoya’s Crystallization Technology (SCT) are to tame the nucleation of a material in solution inside a crystallization reactor as designed by Secoya [1]. Several advantages do exist: control of final crystal size, correct crystal form, inherent narrow size distributions, etc. But how exactly do you start using the technology, and how long does it take to develop a crystallization routine using the SCT technology?
