Superhydrophobic MXene Coating with Biomimetic Structure for Self-Healing Photothermal Deicing and Photoelectric Detector
Two-dimensional transition metal carbides (Ti3C2Tx MXene) have emerged as
new
candidates for applications in multifunctional devices owing to their
outstanding performance. However, these electronic devices are easily
disturbed by water, breakage, oxidation during use, and limited energy
resources. To solve these problems, herein, inspired by nature, a
novel superhydrophobic, healable photothermal deicing and photodetector
(SHPP) with a “papillary structure” is successfully
fabricated for the first time, by a simple layer-by-layer assembly
spraying process with 0D/1D/2D nanomaterials. As a result, the superhydrophobic
modified 2D MXene coating (FM coating) on the SHPP sensor exhibits
outstanding self-cleaning, long-term durability (>20 days), as
well
as excellent photothermal deicing performances under near-infrared
light. Meanwhile, the unique semiembedded nano-ZnO/1D silver nanowire
supports the sensor with desirable photoelectric performance with
UV light and a fast response time (∼1 s), and good cycle stability.
Moreover, benefiting from the transparent self-healing substrate,
the photothermal deicing and photodetector properties can be restored
at room temperature. The bioinspired structures and function mechanisms
offer SHPP sensors great potential for the utilization of clean light
energy, sensing, self-cleaning, anti-icing, and so forth

Rational Design of Metal Organic Framework Nanocarrier-Based Codelivery System of Doxorubicin Hydrochloride/Verapamil Hydrochloride for Overcoming Multidrug Resistance with Efficient Targeted Cancer Therapy
Conventional
organic and inorganic drug nanocarriers suffer from serious drawbacks
such as low drug-storage capacity and uncontrolled release. Moreover,
multidrug resistance (MDR) has been one of the primary causes leading
to chemotherapy failure for cancers. The main reason for MDR is the
overexpressed active efflux transporters such as P-glycoprotein. Here,
zeolitic imidazolate framework ZIF-8, as one of the biocompatible
metal organic frameworks (MOFs), is reported for the first time as
the multidrug carrier to realizing the efficient codelivery of verapamil
hydrochloride (VER) as the P-glycoprotein inhibitor as well as doxorubicin
hydrochloride (DOX) as an anticancer drug to overcome the MDR in addition
to realize the active targeted ability for an efficient anticancer
effect. Uniform ZIF-8 nanoparticles encapsulating DOX and VER are
achieved by a facile one-pot process, in which the VER is used to
overcome the multidrug resistance. Furthermore, methoxy poly(ethylene
glycol)-folate (PEG-FA) is used to stabilize the (DOX+VER)@ZIF-8 to
realize prolonged circulations and an active targeting drug delivery.
In particular, the ZIF-8 exhibits high drug loading content up to ∼40.9%
with a pH-triggered release behavior. Importantly, the PEG-FA/(DOX+VER)@ZIF-8
shows enhanced therapeutic efficiencies with much safety compared
with the direct administration of free DOX both in vitro and in vivo.
Near infrared fluorescent (NIRF) imaging indicates that the PEG-FA/(DOX+VER)@ZIF-8
can increase the drug accumulations in tumors for targeted cancer
therapy. Therefore, the PEG-FA/(DOX+VER)@ZIF-8 multidrug delivery
system can be used as a promising efficient formulation in reversing
the multidrug resistance for targeted cancer therapy
Near-Infrared-Emitting Iridium(III) Complexes as Phosphorescent Dyes for Live Cell Imaging
The three near-infrared-emitting
cationic iridium(III) complexes
[Ir(pbq-<i>g</i>)<sub>2</sub>(N<sup>∧</sup>N)]<sup>+</sup>PF<sub>6</sub><sup>–</sup> (pbq-<i>g</i> =
phenylbenzo[<i>g</i>]quinoline; N<sup>∧</sup>N =
bipyridine (<b>1</b>), 1,10-phenanthroline (<b>2</b>),
4,7-diphenyl-1,10-phenanthroline (<b>3</b>)) have been demonstrated
as phosphorescent dyes in live cell imaging. These complexes with
different ancillary ligands show similar near-infrared (NIR) emission
with λ<sub>max,peak</sub> at 698 nm and λ<sub>max,shoulder</sub> at 760 nm in CH<sub>2</sub>Cl<sub>2</sub> solutions, with a moderate
quantum yield of around 3%. However, these complexes behave quite
differently as NIR dyes for live cell imaging. Complexes <b>1</b> and <b>2</b> exhibit exclusive staining in the cytoplasm with
good cell membrane permeability under excitation at 488 nm, while <b>3</b> gives almost no cell uptake, as further determined by flow
cytometry. Although the lipophilicities of these complexes follow
the order <b>1</b> < <b>2</b> < <b>3</b>,
their cytotoxicities are in the reverse order. The exceptionally low
cytotoxicity of <b>3</b> could be attributed to its poor solubility
in aqueous buffer and thus substantially low exposure dose. This comparative
study suggested that the ancillary ligands could fine-tune the amphiphilicity
and cytotoxicity of the cyclometalated iridium(III) complexes and
thus might play a key role in the design of NIR-emitting iridium(III)
complexes for practical applications in bioimaging
