Recent advancements in drug delivery systems have significant implications not only for healthcare but also for various sectors, including construction. A groundbreaking study published in ‘Macromolecular Materials and Engineering’ explores the potential of modified poly(2-hydroxyethyl methacrylate) (HEMA) particles as carriers for anticancer drugs. The lead author, Shima Ghaffari from the Faculty of Polymer Engineering at Sahand University of Technology in Iran, has investigated how the incorporation of anti-inflammatory drugs like ibuprofen and diclofenac can enhance the efficacy and safety of drug delivery systems.
The research reveals that by synthesizing ibuprofen-HEMA and diclofenac-HEMA monomers, Ghaffari and her team created poly(ibuprofen-HEMA-co-HEMA) (PIHH) and poly(diclofenac-HEMA-co-HEMA) (PDHH) particles. These particles were characterized by their spherical morphology and varying sizes, with PHEMA measuring 298.3 nm, PDHH at 178.8 nm, and the smallest, PIHH, at 85.2 nm. This fine-tuning of particle size is crucial for optimizing drug delivery, as smaller particles can penetrate tissues more effectively.
One of the most compelling findings of the study is the behavior of doxorubicin (DOX), a commonly used chemotherapy drug, when loaded into these modified particles. The release of DOX was significantly higher in acidic environments, which is particularly relevant for targeting tumor tissues that often exhibit lower pH levels. Ghaffari notes, “The ability to control drug release based on pH levels can lead to more effective treatment protocols, minimizing side effects while maximizing therapeutic impact.”
This research has far-reaching implications beyond the laboratory. In the construction sector, the integration of advanced drug delivery systems could transform how we approach health and safety in building environments. For instance, materials engineered with these drug-carrying particles could be used in the development of protective coatings that release therapeutic agents to combat inflammation or infection in construction workers exposed to hazardous conditions.
Moreover, the reduced cytotoxicity observed when using these nanocarriers suggests a potential for safer materials in construction that could be beneficial in maintaining the health of workers and the surrounding community. Ghaffari emphasizes, “Our findings could pave the way for the development of multifunctional materials that not only serve structural purposes but also contribute to health and wellness.”
As the construction industry increasingly adopts innovative materials and technologies, the findings from this study may inspire new products that prioritize both durability and health. The research underscores a growing trend toward interdisciplinary approaches, merging polymer engineering with healthcare applications, ultimately reshaping how we think about materials in various sectors.
