Soft bioelectronics have great potential for the early diagnosis of plant diseases and the mitigation of adverse outcomes such as reduced crop yields and stunted growth. Over the past decade, bioelectronic interfaces have evolved into miniaturized conformal electronic devices that integrate flexible monitoring systems with advanced electronic functionality. This development is largely attributable to advances in materials science, and micro/nanofabrication technology. The approach uses the mechanical and electronic properties of functional materials (polymer substrates and sensing elements) to create interfaces for plant monitoring. In addition to ensuring biocompatibility, several other factors need to be considered when developing these interfaces. These include the choice of materials, fabrication techniques, precision, electrical performance, and mechanical stability. In this review, some of the benefits plants can derive from several of the materials used to develop soft bioelectronic interfaces are discussed. The article describes how they can be used to create biocompatible monitoring devices that can enhance plant growth and health. Evaluation of these devices also takes into account features that ensure their long‐term durability, sensitivity, and reliability. This article concludes with a discussion of the development of reliable soft bioelectronic systems for plants, which has the potential to advance the field of bioelectronics.

Worldwide water paucity and increasing food demand have stressed the agricultural sector for developing strategies to enhance quantity and quality of crop production with limited water resources. In order to pursue a solution of this demand, an efficient, resilient, sustainable, biodegradable, superabsorbent N−S−P carbon dots enriched carboxymethylcellulose nanohydrogel (CDs@CMC nanohydrogel) has been fabricated to study the growth pattern of Vigna radiata with limited water supply in a pot experiment. Characterization techniques like FTIR, TGA, and FESEM analysis established the morphology and structural characteristics of the prepared hydrogel. Sequential variation in the weight % of soil CDs@CMC nanohydrogel ratio was done to study the swelling ratio, water holding, and retention capacities of soil. Further, to ascertain their behavior as soil conditioners during plant growth, these were coupled with varying amounts of N−S− P carbon dots to give Gel-1, Gel-2, and Gel-3. The swelling ratios of Gel-1, Gel-2, and Gel-3 were found to be 2206%, 2582%, and 2712%, respectively, at pH 4, and their water holding capacities were calculated to be 36.7%, 39.5%, and 41.2%, respectively, with 1 wt % of each gel mixed with 50 g of soil, which is higher as compared to 50 g of soil alone (21.2%). The water retention time of the soil increased from 5 to 12 days with the soil mixed hydrogel at room temperature. The hydrogel remained intact, and their swelling capacity shows a slight decline after each consecutive water absorption−release cycle for ten cycles. Further, the seedlings grown in a potting mix containing Gel-1, Gel-2, and Gel-3 survived better than soil, but the best results were shown by Gel-2 with 1 wt % of hydrogel mixed with soil due to the incorporation of a suitable amount of N−S−P CDs in the hydrogel matrices. The ANOVA analysis is also applied for the optimization of the growth parameters of the growth pattern of Vigna radiata, and the study results are supported with the batch studies. Therefore, the environmentally safe, versatile N−S−P carbon dots enriched carboxymethylcellulose nanohydrogel holds promise for sustainable farming applications under water-limited conditions in arid and semiarid regions.

“…18 Such changes due to polar group introduction make GO highly hydrophilic which has been used to load, carry, and release valuable drugs including doxorubicin, quercetin, gefitinib, sumatriptan succinate, and cytarabine, which are used as carriers. 19 Aryl-tetralin-type lignans known as podophyllotoxins (PTOXs) are significant natural toxins found in a variety of plant resins (Figure 1). PTOX along with its structural derivatives is currently gaining more attention, especially in cancer patients' chemotherapy.…”

This study aims to develop a nanodrug delivery system containing podophyllotoxin (PTOX), a known anticancer drug, loaded on graphene oxide (GO). The system’s ability to inhibit α-amylase and α-glucosidase enzymes was also investigated. PTOX was isolated from Podophyllum hexandrum roots with a yield of 2.3%. GO, prepared by Hummer’s method, was converted into GO-COOH and surface-mobilized using polyethylene glycol (PEG) (1:1) in an aqueous medium to obtain GO-PEG. PTOX was loaded on GO-PEG in a facile manner with a 25% loading ratio. All the samples were characterized using FT-IR spectroscopy, UV/visible spectroscopy, and scanning electron microscopy (SEM). In FT-IR spectral data, GO-PEG-PTOX exhibited a reduction in acidic functionalities and there was an appearance of the ester linkage of PTOX with GO. The UV/visible measurements suggested an increase of absorbance in 290–350 nm regions for GO-PEG, suggesting the successful drug loading on its surface (25%). GO-PEG-PTOX exhibited a rough, aggregated, and scattered type of pattern in SEM with distinct edges and binding of PTOX on its surface. GO-PEG-PTOX remained potent in inhibiting both α-amylase and α-glucosidase with IC50 values of 7 and 5 mg/mL, closer to the IC50 of pure PTOX (5 and 4.5 mg/mL), respectively. Owing to the 25% loading ratio and 50% release within 48 h, our results are much more promising. Additionally, the molecular docking studies confirmed four types of interactions between the active centers of enzymes and PTOX, thus supporting the experimental results. In conclusion, the PTOX-loaded GO nanocomposites are promising α-amylase- and α-glucosidase-inhibitory agents when applied in vitro and have been reported for the first time.
