“…Other potential semiconductor candidates for the production of fully natural organic field effect transistors are p‐type beta‐carotene and n‐type indigo (see the Supporting Information Figure S6 and S7). The current limitation of natural organic semiconductors is their intrinsic low mobility (∼4 × 10 −4 cm 2 V −1 s −1 for beta‐carotene and ∼2 × 10 −4 cm 2 V −1 s −1 for indigo, both values obtained from the devices fabricated here) 27. Continued searching for new natural compounds and improved processing (careful cleaning of available materials and optimization of deposition processes) may reveal much higher mobility semiconductors, as observed by the current progress in synthetic high mobility organic semiconductors 28…”

Biocompatible‐ingestible electronic circuits and capsules for medical diagnosis and monitoring are currently based on traditional silicon technology. Organic electronics has huge potential for developing biodegradable, biocompatible, bioresorbable, or even metabolizable products. An ideal pathway for such electronic devices involves fabrication with materials from nature, or materials found in common commodity products. Transistors with an operational voltage as low as 4–5 V, a source drain current of up to 0.5 μA and an on‐off ratio of 3–5 orders of magnitude have been fabricated with such materials. This work comprises steps towards environmentally safe devices in low‐cost, large volume, disposable or throwaway electronic applications, such as in food packaging, plastic bags, and disposable dishware. In addition, there is significant potential to use such electronic items in biomedical implants.

“…50 This property endows it with special characteristics of their function as the semiconductor of type-p like described by Burch et al who described the use of polyunsaturated organic molecules, especially carotenoids, as semiconductors. 51 These results showed that not only do the DCM and MetOH solvents improve the solubility and spinnability of the polymeric solutions, but the semiconductor Bixin was also fundamental to obtaining high-quality electrospun nanofibers.…”

The present work demonstrated an efficient cutaneous wound healing using Bixin-loaded polycaprolactone (PCL) nanofibers as a controlled delivery system. The influence of Bixin (Bix) content on PCL nanofiber, Bix-PCL1(2.5% w/w bix) and Bix-PCL2 (12.5% w/w bix) formation was investigated using electrical conductivity, attenuated total reflectance infrared spectroscopy, X-ray diffraction, thermal analysis, and scanning electronic microscopy. The results showed that a greater bixin concentration resulted in higher polymeric solution electrical conductivity. Moreover, higher polymeric solution electrical conductivity provides lower nanofibers in terms of average diameter than pure PCL nanofibers. In vitro release was largely governed by a diffusion-controlled mechanism. The initial Bixin release domain showed a burst release over the first 10 hours where approximately 30% and 40% of Bixin was released from Bix-PCL1 and Bix-PCL2 nanofibers, respectively. The second kinetic domain was comprised of a continuous and slow Bixin release that led to almost 100% of the Bixin being released within 14 days. The results on excisional wound model in induced diabetic mice indicated that the low concentration of Bixin released from loaded Bix-PCL nanofibers maintain the biological activity of Bixin and is efficient in accelerating the wound healing as well as in reducing the scar tissue area compared with pure PCL nanofibers. Therefore, soft material Bixin-loaded PCL nanofibers are a promising candidate for use in wound dressing. © 2016 Wiley Periodicals, Inc.

“…Bio‐organic field‐effect transistors (BiOFETs) use biomaterials as semiconductors, dielectrics, and substrates. For example, β ‐carotene4 has been applied as semiconductors. DNA‐hexadecyltrimethylammmonium chloride (DNA‐CTMA),5–7 nucleobases,8 and silk9 have been used as gate dielectrics.…”

Chicken Albumen Dielectrics in Organic Field‐Effect Transistors

The application of the biomaterial dielectrics made of thermally crosslinking natural proteins without any additives in fabricating organic electronics is highlighted. The gate dielectrics of organic field‐effect transistors (OFETs) are prepared by the thermal treatment of the chicken albumen film taken directly from a fresh egg. Flexible OFETs and the complementary inverters fabricated with albumen dielectrics are demonstrated.
