Biosensors are an inexpensive, portable and suitable analytical tool, but a required
sample preparation step prevents its use as a field device. One solution to this
challenge is the development of bioanalytical microsystems, in which sample
preparation and biosensing systems modules could be integrated on the same
platform. Thus, they permit the design of easy-to-use and portable analytical
tools. In addition, the combination of research in microfabrication, nanofabrication
technology and material science will become an excellent resource for the devel-
opment of suitable sample preparation steps, as extraction, concentration and
isolation. It might also play a major role in the improvement of the transducer
biorecognition element interface. Under environmental conditions, biosensors
repeated use with complex sample matrices and long-term storage is a remaining
challenge. Maybe the solution to this problem would be found with inexpensive
microbiosensors designed for single use in order to avoid deterioration of the
biosensor elements in complex matrices. Moreover, novel material research
might help to enhance the situation. The researches about biosensors are also a
faster and practical method to produce high-quality and controlled products.
Nano-sized bacterial pores might be used as a simple, fast, effective and selec-
tive way to detect the structure of peptides at the single molecule level. It is a
promising candidate as a nanobiosensors
component designed to detect single
molecules. Aerolysin also denoted nice performance according to its usage on
single peptide molecule detection. According to this point, the foreground of
bacterial nanopores in a nanobiosensor scope is quite broad with the possibility of
finding some other kinds of bacteria that might play a role as an appropriate
component of a nanobiosensor. In addition to this, food materials increased surface
areas by nano-grinding (size reduction operations), so that these materials would be
used as small as possible to get the same benefits from a macro or bigger size, and
they are also more efficient. Mainly, biosensors could be an important alternative to
the traditional methods for the detection of pathogens and toxins in food.
Nanosensors are not only useful for the quality control of flavours and freshness
of products that consumers are able to purchase, but it also has the potential to
reduce the frequency of food-borne illnesses and improve food safety. Such tech-
nology would obviously benefit consumers, food regulators and industry stake-
holders. Packaging industry has been denoted great development because of
nanosensors which are used for detection of microbiological degradation and
toxic substances quickly and effectively and so prevent consumption of spoilage
or contaminated products (Senturk et al.
