There are several very
important reasons the technology we are envisioning does not presently exist.
Even though during the last decade, there have been advances in the design and
development of biosensors, scientists will have to improve the
sensitivity of the sensors. In the case of the ASMS, scientists will have to
precisely control the size of the pores of the sensor to match the size and
shape of the NO. If this is not achieved, other gases will be absorbed by the
sensor, and the ASMS will not accurately measure what it is intended to measure.
Ensure Laser Light
Precautions will also have to be taken to ensure that the laser light
generator does not damage tissue when sending a light beam from the
bracelet to the sensor and back. Today, lasers are only used in
controlled situations by professionals who are trained in their use. In
the future, a laser will need to be developed that will emit a
low-powered light beam that is not strong enough to cause damage to
one’s tissue and can be used by the general public.
Another challenge that will need to be overcome is the expense
associated with the development and use of sophisticated biosensors.
Many of the children that suffer and die from asthma come from poor
urban areas, and it would be unethical for only certain children to be
able to afford the ASMS. Another factor that could prohibit wide use of
our ASMS is the cost that will be involved in training children’s
caregivers. For example, if the data on NO is sent to the nurse’s
office, they must be able to download, read, and interpret the data.
Determining exactly who will pay for the training will be an issue that
would need to be resolved.
