anomaterials have gained importance for their exceptional
properties that may be optical, electrical, chemical,
mechanical or magnetic in nature. Their unique physio-
chemical properties make them most suitable for a wide
range of applications ranging from electronics to healthcare.
This presentation will highlight the latest results on use of
nanomaterials in the development of optical and electrical
lab-on-a chip biosensing platforms from our laboratory.
These biosensors employ unique physio-chemical features of
nanomaterials that are aimed at ultrasensitive detection of
cancer and cardiovascular disease biomarkers in human serum,
pathogenic bacteria, toxic chemicals on a chip, as well as optical
and electrical based nano-biosensing of cellular interactions
with external stimuli. These biosensors are fabricated with
nanomaterials, such as bio-functionalized graphene or carbon
nanotubes, luminescent quantum dots or other metallic
nanoparticles on electrical or optical transducer platforms
that transform biological signals into measurable electrical
or optical signals, respectively. The experience gained from
laboratory scale biosensing is extended to the point-of-care
hand-held diagnostic prototype device fabrication, which has
been successfully tested for detecting multiple cancer and
cardiovascular disease biomarkers in real patient samples.
Finally, the talk also provides an overview of the available
biosensor platforms and integration of nanomaterials for
the detection of various analytes and considerations for
prospects of nanomaterials in the biosensor technology
