intensity increased gradually and reached a plateau (140–260 min),
which could be ascribed to that the glucose has reacted
adequately with GOD. The absorbance intensity increased
continuously and reached a plateau again at 325 min when
more 14 mL of glucose solution (1.0 mM) was added to the
centrifugal tube at 260 min. The results indicated that the
amount of RB molecules released was proportionally depen-
dent on the amount of glucose added. This behavior can be
ascribed to the different degree of ES complex formation along
with the difference in the concentration of glucose, which
implied that the drug delivery for the GOD-capped FMSM
system was mediated by the glucose concentration, thus
affording the enzyme inhibition mechanism-triggered con-
trolled delivery.

To study the selectivity of (MSN-anchor-RB)@GOD for
different monosaccharides, selective response experiments
were carried out accordingly under the same conditions. As
shown in Fig. 3, notably (MSN-anchor-RB)@GOD had high
selectivity for glucose and almost no response for other
monosaccharides such as D-(+)-fructose, D-(+)-mannose
and D-(+)-galactose. This is ascribed to the specific binding
between GOD and glucose.

In conclusion, we have developed a promising ‘‘intelligent’’
controlled delivery system based on the competitive combi-
nation between an inhibitor, an enzyme and a substrate for the
first time. In the present design, we use D-(+)-glucosamine,
glucose oxidase (GOD) and glucose as models to verify this
hypothesis. D-(+)-Glucosamine, an inhibitor of glucose
oxidase (GOD), is anchored outside the pores of MSNs. Then
the mesopores of MSNs are capped by glucose oxidase (GOD)
which can combine with D-(+)-glucosamine to form an EI
complex. Due to the competitive combination between the
substrate, enzyme and inhibitor, effective guest molecules
release was triggered by introduction of glucose. In addition,
(MSN-anchor-RB)@GOD had a perfect selectivity for glucose
over other monosaccharides. Because of the wide use of the
enzyme inhibition mechanism, this proof of principle might
pave the way for a new generation of stimuli-responsive
delivery systems, and could also provide a general route for
the use of other enzymes as ‘‘bio-gates’’ in the field of versatile
controlled delivery nanomaterials.
