Many forward‐looking biomedical, pharmaceutical, and food industry technologies have limited applications owing to the lack of crucial factors: balance of safety and reliability, cost‐efficiency, and suitability for self‐healthcare monitoring. The newly minted field of edible electronics, while at an embryonic stage, is creating great scientific resonance by envisioning a technology which is safe for ingestion, environmentally friendly, cost‐effective, and degraded within the body after performing its function, either digested or even metabolized. Yet there is no shared approach, and the field is currently unified only by the use of food‐derived or edible synthetic functional materials. In order to help shape the field more consistently, the main ideas and perspectives that have been proposed in the recent past are critically curated, underlining what edible electronics is and will be in the future according to the vision. Long‐term opportunities in terms of environmentally friendly smart technologies, remote healthcare monitoring, and the formidable challenges ahead are discussed, covering major issues with respect to safety, materials approval, processing, power supply, communication, and human body interaction. A key point in moving toward such a vision is a strong interdisciplinary cooperation, which is highly encouraged.

“…They showed that, in dry state, BSA-gated pentacene OFETs exhibited a threshold voltage of ca.´16 V, whereas the V TH was reduced to´0.7 V under humid conditions. Very recently, Dumitru et al [107] used a pH-sensitive alginate hydrogel as electrolyte (Figure 17a,b), which is biocompatible and biodegradable. To demonstrate the efficiency of such hydrogels to host bioreceptor without damaging its bioactivity, glucose oxidase was entrapped into the alginate in order to make a biosensor.…”

Electrolytic Gated Organic Field-Effect Transistors for Application in Biosensors—A Review

2016

View full text Add to dashboard Cite

Electrolyte-gated organic field-effect transistors have emerged in the field of biosensors over the last five years, due to their attractive simplicity and high sensitivity to interfacial changes, both on the gate/electrolyte and semiconductor/electrolyte interfaces, where a target-specific bioreceptor can be immobilized. This article reviews the recent literature concerning biosensing with such transistors, gives clues to understanding the basic principles under which electrolyte-gated organic field-effect transistors work, and details the transduction mechanisms that were investigated to convert a receptor/target association into a change in drain current.

Nano- And Microencapsulation - Techniques and Applications

View full text Add to dashboard Cite

Microencapsulation has been the most frequently used technique for several different disciplines such as cell-based therapies and/or transplantation. Technology is based on the idea of combining and coating a material or isolating from an external source. Microencapsulation may be performed with different materials and, among natural biocompatible materials, alginate-based microencapsulation technique is the most appropriate material for microencapsulation. The structural components of alginate materials are the derivatives of alginic acid, which is found in brown algae as an intercellular gel matrix. This alginate is preferred for clinical applications due to its safety in human studies. Therefore, the choice and the combined system need to be carefully optimized to achieve biocompatible application through cell microencapsulation especially for long term. Specifications of alginate such as primary source, isolation process, viscosity, and purity contribute to improve its biocompatibility. Clinically, cell microencapsulation is the major contribution to the field of transplantation by its technique and additionally provides local immune isolation. This chapter discusses the potential benefits of clinically suitable alginates and their applications. This promising technology may highlight its considerable potential for patients that require transplantation and/or replacement therapy in the future.
