PEGDA drug delivery scaffolds prepared with UV curing process

Abstract

Individually tailored drug delivery systems (DDSs) are considered one of the most promising therapeutic tools for the creation of safe and effective treatments. DDSs as a novel approach should be beneficial in curing systemic as well as local ailments, where a high topical concentration of the drug and a reduction of side effects are desirable. It could also be favorable for patients requiring customized treatments, showing atypical profiles of drug metabolism. Development of particular drug delivery devices require the selection of a suitable scaffold material, which should exhibit proper mechanical and biological properties, but also enable adjustment of the drug release according to a specific need. Thus, it is extremely important to expand the knowledge concerning potential DDS components. Poly(ethylene glycol) diacrylate (PEGDA) according to its properties can be easily used as a DDS resin and shaped into a desired structure with the employment of techniques based on photopolymerization, including some novel 3D printing techniques. As a continuation of our previous works, in this paper drug release studies from conventionally prepared PEGDA scaffolds are presented. We have shown that in PEGDA materials, the release profile of the low molecular weight model drug acetylsalicylic acid can be altered by water content. PEGDA as a delivery material should be further investigated to specify its potential as a comonomer and a matrix for pharmaceutical agents.

Magnetically Actuated Drug Delivery Helical Microrobot with Magnetic Nanoparticle Retrieval Ability

“…The drug release degrees were 52.8 ± 0.12, 72.7 ± 2.15, 81.2 ± 2.83, 85.0 ± 3.22, 87.0 ± 3.39, 87.7 ± 3.32, 88.3 ± 3.25, 88.6 ± 3.36, 88.8 ± 3.30, 89.8 ± 3.20, and 91.6 ± 3.29% for 5, 10, 15, 20, and 40 min and 1, 2, 4, 6, 12, and 24 h, respectively. Most of the encapsulated drug was released in a quite short time, which is similar to the drug release of other PEGDA-based drug delivery microrobots. ,, …”

“…The drug release degrees were 52.8 ± 0.12, 72. 25,45,46 Finally, to analyze the possibility of active electromagnetic manipulation of the MNP retrievable microrobot, the magnetization values of the fabricated microrobots were measured by using a vibrating sample magnetometer (VSM, Lake Shore Cryotronics). As a result, the fabricated microrobots had maximum magnetization values of 1.14 memu in the range of −10 to 10 kOe as shown in Figure 2H.…”

Additive Manufacturing and Physicomechanical Characteristics of PEGDA Hydrogels: Recent Advances and Perspective for Tissue Engineering

“…Poly(ethylene glycol) diacrylate (PEGDA) hydrogels have garnered significant interest among hydrogel materials due to their remarkable properties, including hydrophilicity. As a result, they have been extensively explored and applied in various areas, such as three-dimensional (3D) tissue-engineered constructs, bio-sensing mediums, and drug-controlled release matrices [ 17 , 18 , 19 , 20 ].…”
