Biological Sensors Based on 3D Printing Technologies

Dear Colleagues,

With the advent of biological sensor technology, the diagnosis and treatment of diseases have been revolutionized, and the quality of life of individuals has been significantly enhanced. Since the introduction of blood glucose level quantification in the early 1960s, the production technologies and applications of sensors to monitor biological signals have rapidly evolved. Generally, such evolution of sensors to a higher level of sophistication is because of advancements in nano, micro, and macroscale manufacturing methods. They are often miniaturized and multiplexed with several sensing modalities integrated into one device. This is where additive manufacturing, also known as 3D printing, comes into play, a technology that is rapidly evolving and capable of producing functional materials with complex architectures, controlled microstructures, and material combinations. The marriage of 3D printing and biosensors represents a paradigm shift in sensor fabrication, enabling rapid prototyping, intricate geometries, and tailored designs with unparalleled precision. Moreover, 3D printing facilitates the creation of patient-specific biosensors tailored to individual physiological parameters, fostering personalized diagnostics and therapeutics. Beyond healthcare, 3D printing-enabled biosensors hold promise for environmental monitoring, food safety, and industrial applications. From on-site detection of contaminants to real-time quality control in manufacturing processes, these sensors offer cost-effective, scalable solutions for safeguarding public health and environmental sustainability.

This Special Issue explores the convergence of 3D printing technology with biosensing applications, showcasing the transformative potential of this synergistic approach. For this Special Issue, we welcome original research papers as well as reviews on a wide range of topics, including but not limited to the following:

• Novel sensor designs and architectures enabled by 3D printing.
• Advanced materials and fabrication techniques for 3D-printed biosensors.
• Integration of 3D-printed biosensors with microfluidics and other technologies.
• Applications of 3D-printed biosensors in healthcare, environmental monitoring, food safety, and beyond.

The design and development of lab-on-a-chip devices, wearable and plug-and-play biosensors for personalized health monitoring, and integrated sensor arrays for multiplexed detection are of special interest. Reviews should address a thorough analysis of the most recent findings within a specific context or discuss the existing challenges and future directions in the development and deployment of 3D-printed biosensors.
