Book Description
This Special Issue focuses on the synthesis and characterization of hydrogels specifically used as carriers of biological molecules for pharmaceutical and biomedical employments. Pharmaceutical applications of hydrophilic materials has emerged as one of the most significant trends in the area of nanotechnology. To propose some of the latest findings in this field, each contribution involves an in-depth analysis including different starting materials and their physico-chemical and biological properties with the aim of synthetizing high-performing devices for specific use. In this context, intelligent polymeric devices able to be morphologically modified in response to an internal or external stimulus, such as pH or temperature, have been actively pursued. In general, hydrophilic polymeric materials lead to high in vitro and/or in vivo therapeutic efficacy, with programmed site-specific feature showing remarkable potential for targeted therapy. This Special Issue serves to highlight and capture the contemporary progress in this field.

Book Description
Abstract: Hydrogels are a desired material for biomedical and pharmaceutical applications due to their unique swelling properties and highly hydrated structure. To better control the synthesized hydrogels for various applications, it is necessary to have a thorough understanding of hydrogel structure and reaction mechanism. In this study, pH-sensitive hydrogel networks consisting of methacrylic acid (MAA) crosslinked with tri(ethylene glycol) dimethacrylate (TEGDMA) were synthesized by free-radical photopolymerization in the water/ethanol mixture with different ratios under various light intensity. Reaction rate was measured using Photo-Differential Scanning Calorimetry (PhotoDSC) with a modified sample pan designed for handling volatile reagents. A photo-rheometer and a dynamic light scattering (DLS) goniometer were used to follow the changes in viscosity and molecule size of the resin system during photopolymerization. By using the desired functional hydrogels, several drug delivery systems were developed based on the selected integration of a number of micro-manufacturing modules such as soft-lithography, micro-imprinting, and polymer self-folding, to achieve multi-functionalities such as drug protection, self-regulated oscillatory release, enhanced mucoadhesion, and targeted unidirectional release. To evaluate the device performance, adhesion measurement, dynamic flow testing, and targeted unidirectional release were conducted for trans-luminal delivery of two model drugs, acid orange 8 and bovine serum albumin. The self-folding device first attached to the mucosal surface and then curled into the mucus, leading to enhanced mucoadhesion in the mode of "grabbing". Furthermore, the folded layer served as a diffusion barrier, minimizing the drug leakage in the small intestine. The resulting unidirectional release provides improved drug transport through the mucosal epithelium due to localized high drug concentration. The functionalities of the devices have been successfully demonstrated in vitro using a porcine small intestine. The novel delivery devices will be of great benefit to the advancement of oral administration of proteins and DNAs. Since the mucus layer covers many tissues at other specific sites, the devices may be applied for ocular, buccal, vaginal and rectal administrations. The polymer self-folding at the microscale can also be applied as probe arrays for bio/chemical sensing, carriers in cell-based bioreactors, and tissue clamping.
