The rise of novel technological paradigms like the Internet of Things (IoT) has underscored that internet access is no longer exclusive to conventional computers. Various devices and objects now possess the capability to connect. This evolution has led to the emergence of the Internet of Nano-Things (IoNT), an inter-connection of minuscule IoT devices enabled by nanotechnology. This paper delves into the current state of IoNT, amalgamating two swiftly progressing domains: IoT and nanotechnology. Throughout history, technological innovations have consistently shaped human existence, spanning agriculture, healthcare, and transportation. Among these, the IoT has gained prominence, allowing digital entities’ connectivity to the Internet, enabling remote monitoring, control, and conditional automation. The progression of IoT has given rise to IoNT, where nano sized IoT devices play a pivotal role. Despite its novelty, IoNT shares security and privacy vulnerabilities with its larger counterparts. Exploiting these vulnerabilities can have amplified consequences due to the inconspicuous nature of these miniature devices. Recognizing the lack of comprehensive exploration in the IoNT realm, this study aims to fill the gap. It provides an extensive overview of the IoNT ecosystem, highlighting architectural elements, security concerns, and privacy challenges. By presenting a holistic view of IoNT, this study serves as a fundamental reference for future research endeavors in the field.
