This is a question from last year’s Nanochemistry 301 exam:

“1. Self-Assembled Monolayers Biologically active surfactants (e.g., stearyl-?-Dglucopyranoside)
that are capable of selective biorecognition events (selective binding
with concanavalin A) can be immobilised into the surface of a hydrophobic ion
sensing membrane as self-assembled monolayers (SAMS), viz., Muslinkina and
Pretsch, Chem Comms, 2004, 1218-1219. Describe briefly the approach to
characterising these biorecognition events using electrochemical impedance
spectroscopy, and how the Langmuir adsorption isotherm can be used to quantitatively
model the biosensor response process using the measured changes in double layer
capacitances of the hydrophobic ion sensing membrane. Your answer should include
a diagram of a typical Bode phase plot originating from a biorecognition event, along
with the relevant mathematical equations and experimental plots that are used to
characterise the adsorption process.
(15 marks)”

I am very happy that at this stage I can actually answer that.

*EDIT*: Man, I just totally owned that exam. Like. Totally. omg.
