Nanotechnology for Biosensors: A Review

Aishwaryadev Banerjee

2021

Biosensors are essential tools which have been traditionally used to monitor environmental pollution, detect the presence of toxic elements and biohazardous bacteria or virus in organic matter and biomolecules for clinical diagnostics. In the last couple of decades, the scientific community has witnessed their widespread application in the fields of military, health care, industrial process control, environmental monitoring, food-quality control, and microbiology. Biosensor technology has greatly evolved from the in vitro studies based on the biosensing ability of organic beings to the highly sophisticated world of nanofabrication enabled miniaturized biosensors. The incorporation of nanotechnology in the vast field of biosensing has led to the development of novel sensors and sensing mechanisms, as well as an increase in the sensitivity and performance of the existing biosensors. Additionally, the nanoscale dimension further assists the development of sensors for rapid and simple d...

Micro- and Nanotechnology in Biosensor Research

Louis Tiefenauer

Chimia International Journal For Chemistry, 1999

Biosensor research is strongly interdisciplinary as it requires experience in chemistry, biochemistry, biology, material science, electronics and engineering. The recent progress in micro-and nanotechnology allows to miniaturize complex systems as well as to address problems at a molecular level. The architecture and even the function of single molecules on a sensor surface have been investigated and can to some extent even be predetermined. At present, microtechnology is well established in the production of micro-fluid transport systems and has a high potential for cell-culturing and monitoring devices in the future. Three different running projects are presented which illustrate the usefulness of micro-and nanotechnology for biosensor research: 1)Investigations on amperometric immunosensor devices, 2) the measurement of binding forces of individual antigen-antibody pairs, and 3) the fabrication of microchannels suitable for neuron-cell growth and recording. Big efforts, however, will be required to integrate the recognition element of a sensor into a device for an intended application

Chemistry Proceedings, 2021

The growing human population and the discovery of new diseases and emerging pandemics have increased the need for healthcare treatments and medications with innovative designs. The emergence of nanotechnology provides a platform for novel diagnostic and therapeutic in vivo non-invasive detection and treatment of ailments. It is now the era of the Internet of things (IoT), and data acquisition and interpretation from various parts of the human body in real time is possible with interconnected sensors and information transfer devices. Miniaturization, low power consumption and price with compatibility to existing network circuits are essential requirements in the IoT. Biosensors made of nanostructured materials are the ideal choice due to the unique structural, chemical and electronic properties of these materials with the advantage of a large surface-to-volume ratio, which makes them very successful for use as sensors for the detection of diseases, drug carriers, filters, fillers and...

One of the reasons for the emergence of nanotechnology is the extraordinary knowledge-based and technical development in diverse areas, such as pharmacy and biomedicine. One nanometer can be described as one billionth of a meter and three times smaller than micron [3]. Over the past few years, nanotechnology has been instrumental in the field of medicine and its development. Studies show that a wide range of Nanomaterials has emerged that have biomedical

New Micro -and Nanotechnologies for Electrochemical Biosensor Development

ea me

1.1 Introduction Over the last decade, great attention has been paid to the inclusion of newly developed nanomaterials such as nanowires, nanotubes, and nanocrystals in sensor devices. This can be attributed to the ability to tailor the size and structure, and hence the properties of nanomaterials, thus opening up excellent prospects for designing novel sensing systems and enhancing the performance of bioanalytical assays [1]. Considering that most biological systems, including viruses, membranes , and protein complexes, are naturally nanostructured materials and that molecular interactions take place on a nanometer scale, nanomaterials are intuitive candidates for integration into biomedical and bioanalytical devices [2, 3]. Moreover, they can pave the way for the miniaturization of sensors and devices with nanometer dimensions (nanosensors and nanobiosensors) in order to obtain better sensitivity, specifi city, and faster rates of recognition compared to current solutions. The chemical, electronic, and optical properties of nanomaterials generally depend on both their dimensions and their morphology [4]. A wide variety of nanostructures have been reported in the literature for interesting analytical applications. Among these, organic and inorganic nanotubes, nanoparticles, and metal oxide nanowires have provided promising building blocks for the realization of nanoscale electrochemical biosensors due to their biocompatibility and technologically important combination of properties, such as high surface area, good electrical properties, and chemical stability. Moreover, the integration of nanomaterials in electrochemical devices offers the possibility of realizing portable, easy-to-use, and inexpensive sensors, due to the ease of miniaturization of both the material and the transduction system. Over the last decade, this fi eld has been extensively investigated and a huge number of papers have been published. This chapter principally summarizes progress made in the last few years (2005 to date) in the integration of nanomaterials such as carbon nanotubes (CNTs), nanoparticles, and polymer nanostructures in electrochemical biosensing systems.
