Abstract Recent advancements in morphology control and surface functionalization of mesoporous silica nanoparticles (MSNs) have enhanced the biocompatibility these materials with high areas pore volumes. Several recent reports demonstrated that MSNs can be efficiently internalized by animal plant cells. The organic moieties or other nanostructures brings controlled release molecular recognition capabilities to for drug/gene delivery sensing applications, respectively. Herein, we review...
Mesoporous silica nanoparticles (MSNs) are introduced as chemically and thermally stable nanomaterials with well-defined controllable morphology porosity. It is shown that these particles possess external internal surfaces can be selectively functionalized multiple organic inorganic groups. On the basis of characteristics, biocompatibility silica, their efficient uptake by mammalian cells, MSNs proposed nanodevices for controlled release drugs genes into living cells.
Stand and deliver! The release of pore-encapsulated fluorescein molecules from a core/shell mesoporous silica nanorod/superparamagnetic iron oxide nanoparticle carrier in the presence an external magnetic field only response to cell-produced antioxidants indicates promise for such systems controlled-release drug delivery.

Recent advancements in controlling the surface properties and particle morphology of structurally defined mesoporous silica materials with high area (>700 m2 g−1) pore volume (>1 cm3 have significantly enhanced their biocompatibility. Various methods been developed for functionalization both internal exterior surfaces these silicates a tunable diameter ranging from 2 to 30 nm narrow size distribution. Herein, we review recent research progress on design functional stimuli-responsive...
The development of a rapid and sensitive infectious disease diagnostic platform would enable one to select proper treatment contain the spread disease. Here we examined feasibility using quantum dot (QD) barcodes detect genetic biomarkers bloodborne pathogens HIV, malaria, hepatitis B C, syphilis. fragments from these were detected in less than 10 min at sample volume 200 μL with detection limit femtomol range. A next step for advancement QD barcode technology clinic will require validation...
Halt, abliefern! Fluoresceinmoleküle, die in den Poren eines Kern-Schale-Systems aus mesoporösen Siliciumoxid-Nanostäbchen und superparamagnetischen Eisenoxid-Nanopartikeln eingeschlossen sind, werden Gegenwart externen Magnetfelds freigesetzt, doch nur als Antwort auf Zellen produzierte Antioxidantien. Das macht ein solches System für kontrollierte Wirkstoffabgabe interessant.
The presence of gum tragacanth in calcium alginate beads makes them more osteo-conductive and proangiogenic.
Success of bone tissue engineering (BTE) relies on the osteogenic microarchitecture biopolymeric scaffold and appropriate spatiotemporal distribution therapeutic molecules (growth factors drugs) inside it. However, existing technologies have failed to address both issues together. Keeping this perspective in mind, we developed a novel three-dimensional (3D) implant prototype by stacking hexagonal close packed (HCP) layers calcium alginate beads. The HCP arrangement beads lead patterned array...
Multimodal therapeutic approach towards colorectal cancer (CRC) holds great promise. There is, however, no convincing strategy reported to date that employs a multimodal in CRC treatment. The present study reports an intense green-emitting core–shell photoluminescent upconversion (CSGU) nanocrystal engineered synergistically perform photodynamic and enzyme-triggered delivery of the chemotherapeutic agent for enhanced outcome on HT-29 colon carcinoma cells vitro. activity is achieved by...
Biomaterial induced activation of vascular endothelial growth factor (VEGF) pathway for angiogenesis is now gaining recognition as an effective option tissue engineering.
Gradient concentric rings with unprecedented regularity, formed by drying a polymer solution from sphere-on-Si geometry, are utilized as templates for preparing wide variety of metal or oxide rings. This simple yet novel approach affords cost-effective means to produce in fashion.
A simple one-step flow focusing method was used to embed both magnetic nanoparticles and quantum dots in microbeads controlled ratios generate a large library of molecular barcodes for biological applications.
