|
What is the prevalence of diabetes? |
WHO estimates 420 million people worldwide |
|
|
What is the next potential type of biosensor being designed and who designed it? |
Yan Feng et al. highly sensitive, accurate, flexible and affordable biological sensor that can detect glucose levels in saliva. |
|
|
What type of biosensor is the newly designed biosensor and what does it detect? |
Electrochemical - detects ions, lactose and glucose |
|
|
What is the main challenge of the new biosensor? |
To create a selective biosensor that is only sensitive to a specific substance, such as glucose, because it can also pick up electrical currents from other biochemicals. |
|
|
Describe the newly designed glucose biosensor? |
Glucose oxidase enzyme is only sensitive to glucose, The enzyme is coated with two types of polymer layers to prevent interference form other substances in saliva, increasing its selectivity and sensitive. |
|
|
What concentrations of glucose can the new biosensor measure? |
10^-5 mmol/L - 1000x more sensitive that conventional measurement |
