It
was
conceivable
that,
if
three
promising
concepts
(molecular
imprinting,
magnetic
separation,
and
optical
detection)
were
combined,
a
novel
fluorescein
isothiocyanate
(FITC)-labelled
magnetic
MIP
could
be
constructed
that
exhibits
high sensitivity
and selectivity.

As
a
reference
,
non-
imprinted
polymer
coated
beads
(Fe

O

@SiO

-Dye-NIP),
which
did
not
contain
the
template,
were
also
prepared
in
parallel
with
the

-Dye-MIP by
using the same synthetic protocol.

The polymer
layer had a thickness of about 5.7 nm and appeared
to be uniform
(top
inset),
which
could
be
attributable
to
the
intrinsic
characteristics
of
the
controlled/living
polymerization mechanism of RAFT.
4.
The
EDS
analysis
was
also
conducted
to
confirm
the
existence
of
imprinted
polymer.
5.
When
the
microspheres
are
placed
in
an
external
magnetic
field,
efficient
magnetic
separation is observed in a short time (about 85
s).
6.
The
results
showed
that
none
of
the
compounds
being
evaluated
gave
any
significant interference.
7.
A piece of
polypro-pylene membrane was
soaked
in
the polymerization solution
for 5 min
8.
It showed that the fluorescence
intensity was accelerated
along
with
the increase
of
reaction time till 6h and then decreased.
9.
Short reaction
time produced few specific sites,
whilst
long reaction time
would
cause
higher
crosslinking
degree
of
polymer
which
may
block
the
imprinted
cavities.
10.
Molecular
recognition
selectivity
is
an
important
parameter
in
evaluating
imprinted
material
11.
These kinds of thermosensitive protein-
imprinted beads can be used to control the
uptake and release of the target
protein
from a mixture of proteins.
12.
Molecular
non-imprinted beads
(NIP beads) were
generated in
the same
way as
the MIP beads but
without addition of the template protein.
13.
elemental
analysis was performed with the Vario Micro cube
elemental analyzer
(Elementar, Hanau,
Germany) to
monitor
the
surface composition of the beads.
14.
The
afore
mentioned results
demonstrated that two-layer structures of the
coated
MIP beads have different
adsorption characteristics compared with the MIP
beads.
15.
An
MIP-NiO
magnetically
controlled
glassy
carbon
electrode
(GCE),
hereafter
denoted as
MIP-NiO/GCE, was
used as the working electrode.
16.
As a result,
the NiO nanoparticles were able to be isolated
from the solution by an
adscititious
magnet.

17.
To evaluate
the effect of the buffer solution, the
performances of the MIPs sensors
were
examined by readsorption (or rebinding) of
chlortoluron
in the following

，

.
18.
The catalytic
current decreased until
almost
constancy
with increased readsorption
time.
19.
Consequently, the readsorption time of
10 min was used
in all subsequent
assays
.
20.
Some
compounds
of
chlortoluron
analogs
such
as
isoproturon,
difenoxuron,
veburon, and fluometuron were tested
by mingled with
chlortoluron
separately in
the competition
procedure.

Table

shows
that
the
recoveries
of
this
sensor
were
from
96.9%
to
104.7%,
which
signifies
good
practicability.

The presence
of Cr(III) is thought to
originate
from
the chemical interactions of
Cr(VI) ions with GOF/Fe

2. the
GOF/Fe3O4 showed an excellent absorption
performance for the removal of
Cr(VI)
ions with maximum absorption capacity (258.6 mg/g)
and fast adsorption
rate (100 mg/L, 20
min) at pH 2, which significantly
outperformed
the reported
2D graphene-based adsorbents and other
conventional adsorbents.

There are
a great deal of
efforts to
enhance the structural stability of the composite
membranes, such as establishing
covalent or ionic linkage between active layer
and the substrate, or forming an
adhesive layer to link the active layer and the
substrate.
25.
There were evident differences about
the membranes' structure when comparing
