Magnetic Nanocarriers with ICPTES- and GPTMS-Functionalized Quaternary Chitosan for pH-Responsive Doxorubicin Release Open
Smart nanocarriers are being increasingly explored to improve the performance selectivity of cancer chemotherapy. Here, two pH-responsive magnetic nanocarriers were developed using quaternary chitosan (HTCC) functionalized with 3-(triethox…
Multifunctional bionanocomposites for trace detection of water contaminants Open
We report here research on magneto-plasmonic bionanocomposites (Fe₃O₄@SiO₂/SiκCRG/Ag) designed for the detection of water contaminants using surface enhanced Raman scattering (SERS) methods. These new substrates comprise a ferrimagnetic co…
An Ammonite Preserved in the Upper Pliocene Lower Tejo River Deposits of Quinta Do Conde (Southwest Portugal) Open
A cast is an object that results from a fossilization process that is considerably rare in nature. For a cast to be produced, secondary diagenetic processes during and after fossilization are normally involved. Natural casts are formed whe…
Tuning adsorption capacities of hybrid mesoporous silica nanospheres and adsorption mechanism study for sulfamethoxazole and diclofenac removal from water Open
The functionalization of mesoporous silica nanospheres and mesoporous hybrid core–shell magnetic silica nanospheres has been carried out through post-synthetic procedures, and these materials have been tested as adsorbents for the removal …
Magneto-plasmonic bionanocomposites for on-site SERS detection of water contaminants Open
Bionanocomposites based on chitosan have been explored as magneto-plasmonic nanosorbents for the SERS detection of organic molecules in spiked water.
High yttrium retention in magnetite nanoparticles functionalized with hybrid silica-dextran shells Open
Oncologic thermoradiotherapy combines hyperthermia and radiotherapy treatments, and their simultaneous use has been shown to be more efficient than their alternate use. Targeted and simultaneous thermoradiotherapy can be achieved with radi…
Transition metal-modification of carrageenan-silica hybrids by a sol–gel method Open
Transition metal (TM)-modification of silica matrices are found in numerous materials for diverse applications. In other related hybrid materials, one tries to explore properties that result from combining the silica network with organic m…
Enhanced Removal of Non-Steroidal Inflammatory Drugs from Water by Quaternary Chitosan-Based Magnetic Nanosorbents Open
Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most common pharmaceuticals used worldwide. They are widely detected in natural waters due to their persistence in wastewater treatment, and their removal is desirable in wastewa…
Magnetic Driven Nanocarriers for pH-Responsive Doxorubicin Release in Cancer Therapy Open
Doxorubicin is one of the most widely used anti-cancer drugs, but side effects and selectivity problems create a demand for alternative drug delivery systems. Herein we describe a hybrid magnetic nanomaterial as a pH-dependent doxorubicin …
Trimethyl Chitosan/Siloxane-Hybrid Coated Fe3O4 Nanoparticles for the Uptake of Sulfamethoxazole from Water Open
The presence of several organic contaminants in the environment and aquatic compartments has been a matter of great concern in the recent years. To tackle this problem, new sustainable and cost-effective technologies are needed. Herein we …
The controlled synthesis of complex hollow nanostructures and prospective applications <sup/> Open
Functionality in nanoengineered materials has been usually explored on structural and chemical compositional aspects of matter that exist in such solid materials. It is well known that the absence of solid matter is also relevant and the e…
Magnetic Hybrid Nanosorbents for the Uptake of Paraquat from Water Open
Although paraquat has been banned in European countries, this herbicide is still used all over the world, thanks to its low-cost, high-efficiency, and fast action. Because paraquat is highly toxic to humans and animals, there is interest i…
