Strategic Role of Nanobiosensor in Food:
Benefits and Bottlenecks
Semih Otles and Buket Yalcın
Abstract Nanotechnology has recently become one of the most exciting forefront
fields in biosensors fabrication. Nanotechnology has been changing the area of
biosensor for many kinds of fields as food. Nanobiosensor, an integration of
molecular engineering, physical sciences, chemistry, biology and biotechnology,
holds the possibility of manipulating and detecting molecules and atoms using
nano-devices/machines, which have the potential for a wide range of both domestic
and industrial applications. The role of nanobiosensors in food analysis and detec-
tion of chemical and biological compounds in food is an interesting and important
area. Biosensors permit the detection of a wide spectrum of analyte in complex
sample matrices and have denoted great promise in areas like food analysis. There
has been a steadily growing use of biosensor technology for the detection of food
contaminants such as food dyes, processing contaminants, veterinary drugs, marine
toxins and mycotoxins. On the other hand, there are both some benefits and
bottlenecks of nanobiosensors in food fields.

Introduction
Nanotechnology has recently become one of the most exciting forefront fields in
biosensors fabrication. Nanotechnology could be defined as the creation of func-
tional materials, systems and devices through control of matter at the 1-100 nm
scale. By the way, nanotechnology is also a rapidly developing area of science and
technology, which is usually interested in particles between 1 and 100 nm. This
technology denotes great potential to provide new physical, chemical and biolog-
ical features to materials in atomic or molecular scale (Otles and Yalcin
2013
). A
wide range of nanoscale materials of different compositions, sizes and shapes are
now available. The enormous interest in nanomaterials is driven by their many
desirable properties. Use of nanomaterials in biosensors permits the use of many
