ECEN 414 Exam 1 questions and
answer stated A+
Biosensors - correct answer ✔✔ Devices that combine a biologically sensitive element with a
physical or chemical transducer to detect the presence of specific compounds in a given
external environment
Bio-recognition systems, typically enzymes or binding proteins on the surface of a physical or
chemical transducer
Transducer - correct answer ✔✔ A system the converts one type of energy to another
Bio-recognition Systems - correct answer ✔✔ Enzymes
Antibodies
DNAs
Bacteria
Single cell organisms
Tissues of higher organisms
Biosensor Applications - correct answer ✔✔ Medical research and diagnosis
Point-of-care testing
Food and environmental testing
Bio-tech applications
Micro-Electro-Mechanical-System (MEMS) - correct answer ✔✔ Miniaturized devices and
systems that have electrical and mechanical components
, Manufactured using fabrication technologies from the semiconductor industry
BioMEMS - correct answer ✔✔ Lab-on-a-chip
Has all the stages of chemical analysis
Microfluidics - correct answer ✔✔ Fluidic systems in which smaller size scale causes changes in
fluid behavior
Laminar Flow
large surface to volume ratio
Droplet Microfluidics - correct answer ✔✔ Two-phase flow
oil in water
water in oil
Why Miniaturization? - correct answer ✔✔ Need to move analysis closer to the user
EX: pregnancy test, blood glucose tests
Advantages:
Better performance due to smaller sample
Low power consumption
