Nanoantennas and Nanoradars: The Future of Integrated Sensing and Communication at the Nanoscale
January 14, 2024 - One such instance emphasizes on the employement of dielectric dot radiators, represented by the optical dot antenna (ODA), as a flexible way for arranging electromagnetic properties, thereby supporting transmission and directivity within bull’s eye structures applicable to biosensors and nanophotonics [231]. Equally notable is the integration of plasmonic nanoantennas, manufactured by the indium-tin oxide (ITO) nanorod arrays, which, as an alternative to conventional plasmonic materials like gold and silver, avoid their inherent limitations—such as high loss and cost [234]. These examples are only a few out of many in the literature.

r/transhumanism on Reddit: Intra-Body Molecular Communication via Blood- Tissue Barrier for Internet of Bio-Nano Things (IOBNT)
November 17, 2024 -
In the Intra-body nano networks, the bio-nanomachines enter the body through injection into the blood and then navigate autonomously throughout the body to reach the blood capillary network. The blood tissue barrier inside the body forms the main communication pathway for molecular information exchange between the nanomachines as well as between the intra-body nano network and the Bio-Cyber interface in the IoBNT network. Watch the video to learn more about how the Brain Tissue Barrier, the Blood Brain barrier, the Intra-body nanonetwork, and The Bio-Cyber interface all work together in this research in mimicking biology for nano communication.

YES I did use chatGPT to parse the paper: It's 100% simulation and modeling—no wet lab, no hardware, no live implants. Just molecules in silico. Here's what they did do: Built a COMSOL Multiphysics numerical model of molecule transport across capillary walls. Developed a custom MATLAB particle simulator to validate the model—tracks molecule-by-molecule movement under diffusion, flow, degradation, and capillary permeability. Compared the two to ensure the math holds up. Ran a bunch of simulations changing parameters (flow speed, distance, emission duration, permeability, etc.) to see how they affect the molecular "signal" received. What they did not do: No experiments with nanorobots or nanomachines. No animal or human testing. No physical bio-cyber interface prototypes. No integration with actual sensors or drug delivery systems.It's 100% simulation and modeling—no wet lab, no hardware, no live implants. Just molecules in silico. It's a toolbox contribution: if someone were building a real nano-drug-delivery system, this could guide where to place the transmitter, how fast to release the drug, how to interpret signals, or even how to design the capillary interface. Conclusion: Its a modeling tool, nothing more.

Beamforming optical antenna arrays for nano-bio sensing and actuation applications - ScienceDirect
May 21, 2021 - Despite the small wavelength, current technologies used in these fields are not nanoscale and, in many occasions, not wireless, thus limiting the potential applications. For example, the majority of groups currently working on state of the art plasmonic nano-sensors use bulky equipment setups to read the data from sensors in ex-vivo measurements (e.g., in blood samples [1]).

Electromagnetic Nanonetworks Beyond 6G: From Wearable and Implantable Networks to On-chip and Quantum Communication
May 14, 2024 - The latter aspects are of fundamental relevance for a nanonetworking paradigm where biomedical applications were paramount [7]. On the other hand, electromagnetic communications in the nanoscale were studied given their higher capacity and wider applicability, also spurred in part by the advancement in miniaturized plasmonic antennas in the terahertz and optical ranges [8]. Hence, the concept of electromagnetic nanonetworks (the main focus of this manuscript) was born.

Materials Perspectives of Integrated Plasmonic Biosensors - PMC
An important area that can benefit from the advances of plasmonic doped semiconductors is surface-enhanced Raman spectroscopy (SERS), which is a technique that spectrally analyzes the chemical and biological properties of analytes via deep interactions at the plasmonic surface level [130]. In [127], the authors demonstrate the use of an InAsSb antenna array deposited on gallium antimonide (GaSb) for SERS of vanillin (Figure 5b). The field enhancement concentrated around the corners of the nanoantennas is used as the main property for sensing.
