Continuous Microfluidic Manufacture of Nano-in-Microparticles Combining 3D-Printed Micromixers and Spray Drying.
Article in Pharmaceutical research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeConventional nanoparticle manufacturing techniques remain costly, labor-intensive, and difficult to scale, while also being subject to batch-to-batch variability. These limitations hinder their clinical translation, particularly in first-in-human trials. Emerging transformative technologies such as microfluidics and three-dimensional (3D) printing offer opportunities to develop agile, continuous, and scalable manufacturing processes. This study aims to demonstrate the feasibility of continuous microfluidic production of nanoparticles using customizable 3D-printed chips, integrated with atomization technologies, to generate solid nano-enabled controlled release therapies.
methods3D-printed microfluidic chips were designed using computational fluid dynamics (CFD) to optimize flow characteristics. Nifedipine (NFD)-loaded nanoparticles were continuously manufactured with Eudragit L-100 and subsequently embedded into pullulan microparticles by spray-drying, yielding nano-in-microparticles (NIM). Particle size, encapsulation efficiency, solid-state properties, permeability, and release kinetics were assessed in ex vivo Franz cell studies across porcine intestinal membranes.
resultsContinuous microfluidic processing produced NFD-loaded nanoparticles with 95% encapsulation efficiency. Spray-drying yielded spherical pullulan-based NIMs of ~ 10 µm, which, upon rehydration, released NFD nanoparticles of ~ 100 nm. The nanoparticles retained their amorphous state and displayed a three-fold increase in intestinal permeability compared to free drug, accompanied by a three-fold reduction in lag time. Release studies demonstrated reduced burst release and a sustained zero-order release profile over 24 h, favorable for blood pressure maintenance therapy.
conclusionsThe integration of 3D-printed microfluidic chip design with continuous manufacturing and spray-drying enables scalable production of solid nano-enabled therapies. The NFD-loaded NIMs demonstrated enhanced permeability and controlled release, supporting the potential of this platform for the clinical translation of nanomedicines.
