Transparent conducting electrodes (TCE) are a fundamental component in many modern devices
Increasing demand for the devices led to spurring demand for TCEs
Market for TCEs is expected to reach
for
$2.5
billion
by
2025

Slide17Colorimetric Biosensing-1In developing countries, the problem of accessibility to
health care is greatly exacerbated, little or no access to even the basic health services due to financial limitations, a shortage of skilled
personnel, and a lack of and a lack of infrastructure
In
addition to basic medical tests and
screening
for
chronic disease, affordable test kits for infectious
diseases
can
be a life-saving intervention in many developing
countries,
where
millions die every year due to inadequate diagnosis
and
these
tests could help prevent epidemics from turning
into pandemicsAlso rapid and low-cost methods
of analysis for food safety and water quality, counterfeit medicine, and veterinary testing are also
needed.
