A simple and sensitive ̄uorimetric method for the determination of epinephrine is described. The method is based on the reaction of epinephrine with o-phenylenediamine in alkaline medium. The addition of 0.2% (v/v) acetone enhances the ̄uorescence 50-fold. Under optimum conditions, a linear relationship was obtained between the ̄uorescence intensity and(More)
Multifunctional and multiresponsive hydrogels have presented a promising platform to design and fabricate smart devices for application in a wide variety of fields. However, their preparations often involve multistep preparation of multiresponsive polymer precursors, tedious reactions to introduce functional groups or sophisticated molecular designs. In(More)
