Quercetin-Based Advanced Delivery Systems - From Multimodal Nano-theranostics to Microneedles: a Recent Update on Their Preclinical Studies.
Review in International journal of nanomedicine, 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
Quercetin is a naturally derived flavonoid that has received growing attention for its wide range of pharmacological activities such as strong anticancer, antimicrobial, anti-inflammatory, and antioxidant effects. Its multiple functions and natural bioactivity make it an appealing therapeutic candidate. However, the clinical use of quercetin is still limited by issues like poor water solubility, low bioavailability, fast metabolism, and difficulties in achieving targeted delivery. Recent research has aimed to overcome these challenges through innovative formulation strategies like nanoencapsulation, polymeric carriers, 3D printing, microneedle scaffolds and surface modification. These approaches improve stability, boost bioavailability, and allow for targeted therapeutic effects. Traditional theranostic systems that use nanoparticles, quantum dots, or linked biomolecules have enhanced precision medicine by merging diagnostic imaging methods, such as MRI, PET, and fluorescence, with treatment options like targeted drug delivery and photothermal therapy. Yet, these systems face issues related to biocompatibility, cost, biodegradability, and targeting precision. Platforms based on quercetin are emerging as a promising alternative to tackle these problems. Despite their potential, this area is largely uncharted, and, to our knowledge, no thorough review has focused on quercetin's role in multifunctional theranostic systems. This review offers a systematic look at the design strategies, biomedical uses, and potential for quercetin-based theranostics. We discuss key challenges, such as achieving controlled/stimuli-responsive delivery, validation in higher animal studies, scale-up and to emphasize future directions for evolving quercetin-based platforms as next-generation nano-theranostics.
