Many diseases are characterized by the presence or absence of multiple biomarkers, and the ability to detect and quantify several targets in a single assay would greatly enhance diagnostic capabilities. However, integrating multiple sensing modalities into a single nanorobot while avoiding cross-reactivity and maintaining individual sensor performance remains a complex challenge.

The integration of power sources and propulsion mechanisms into nanorobots without compromising their size or detection capabilities is also a critical issue. Ensuring that nanorobots have sufficient energy to perform their sensing functions and navigate through biological fluids for extended periods is essential for effective diagnostics. Researchers are exploring various energy harvesting techniques and efficient propulsion methods to address this challenge.

Lastly, the reproducibility and scalability of nanorobot production present significant obstacles. Achieving consistent performance across large numbers of nanorobots is crucial for reliable diagnostics. Current fabrication techniques often struggle to produce large quantities of nanorobots with uniform properties and sensing capabilities. Developing scalable manufacturing processes that maintain nanoscale precision and functionality is a key area of focus in the field.

The nanorobotics diagnostics field for biomarker detection sensitivity is in an early growth stage, with significant potential for expansion.
