The neuromorphic nature of the resistive switching in TiO2 memristors has triggered a series of studies addressing their functional coupling with living biological systems. The common features of the electroconductive behavior of memristive and biological neural networks have been revised in terms of physical, mathematical, and stochastic models (Chua, 2013Feali and Ahmadi, 2016). The memristive electronics was shown to support important synaptic functions such as spike timing-dependent plasticity (Jo et al., 2010Pickett et al., 2013). Recently, a memristive simulation of important biological synaptic functions such as non-linear transmission characteristics, short-/long-term plasticity, and paired-pulse facilitation has been reported for hybrid organic–inorganic memristors using Ti-based maleic acid/TiO2 ultrathin films (Liu et al., 2020). In relation to this, functionalized TiO2 memristive systems may be in competition with the new generation of two-dimensional memristive materials such as WSe2 (Zhu et al., 2018), MoS2 (Li et al., 2018), MoS2/graphene (Kalita et al., 2019), and other systems (Zhang et al., 2019a) with ionic coupling, ionic modulation effects, or other synapse-mimicking functionalities. Furthermore, the biomimetic fabrication of TiO2 (Seisenbaeva et al., 2010Vijayan and Puglia, 2019Kumar et al., 2020) opens up new horizons for its versatile microstructural patterning and functionalizations.

In conclusion, food-safe titanium dioxide has played a significant role in enhancing the visual appeal of our food, but its use is continually being reassessed in light of new scientific evidence. Regulatory bodies worldwide are vigilant in ensuring its safety, and the industry is adapting to meet changing standards and consumer demands. As we move forward, it is crucial to strike a balance between innovation and safety, ensuring that the food we consume is not just visually appealing but also free from potential harm.
