Smart Microfluidics: a curated dataset of microfluidic liposome formulations with cross-laboratory validation for machine-learning applications

Published in Data in Brief, 2026

This dataset compiles microfluidic liposome production experiments from two laboratories, linking formulation parameters and operating conditions with vesicle size and polydispersity measurements. After a standardized Python-based preprocessing workflow, the harmonized dataset (304 formulations plus 12 validation runs) supports machine-learning benchmarking and evaluation of cross-laboratory reproducibility. Code available here. Read more

Machine Learning-Guided microfluidic optimization of clinically inspired liposomes for nanomedicine applications

Published in International Journal of Pharmaceutics, 2025

This article discusses the transformative role of machine learning in optimizing liposome development, a process traditionally limited by its complexity, high cost, and time-intensive experimentation. By analyzing over 300 experimental conditions using a microfluidic production platform inspired by the formulations of Doxil® and Marqibo®, the study demonstrates how predictive models can efficiently determine key liposome characteristics such as particle size and polydispersity index. An open-source simulation tool was also developed to allow researchers to virtually design and test formulations, reducing the need for extensive laboratory work. The models were validated through independent experiments, confirming their robustness and adaptability. Code available here with an associated app here. Read more

On the Effects of Small Graph Perturbations in the MaxCut Problem by QAOA

Published in AVS Quantum Science, 2025

In this article we investigate the Maximum Cut (MaxCut) problem on different graph classes with the quantum approximate optimization algorithm (QAOA) using symmetries. In particular, heuristics on the relationship between graph symmetries and the approximation ratio achieved by a QAOA simulation are considered Read more
