Sol–gel chemistry offers a flexible approach to obtaining diverse range of materials. It allows differing chemistries be achieved as well offering the ability produce wide nano-/micro-structures. The paper commences with generalized description various sol–gel methods available and how these control bulk properties end products. Following this, more detailed biomedical areas where materials have been explored found hold significant potential. One interesting fields that has developed...

Drug molecules with lack of specificity and solubility lead patients to take high doses the drug achieve sufficient therapeutic effects. This is a leading cause adverse reactions, particularly for drugs narrow window or cytotoxic chemotherapeutics. To address these problems, there are various functional biocompatible carriers available in market, which can deliver agents target site controlled manner. Among developed thus far, mesoporous materials emerged as promising candidate that variety...

Abstract The proinflammatory chemokine interleukin-8 (IL-8) is undetectable in androgen-responsive prostate cancer cells (e.g., LNCaP and LAPC-4), but it highly expressed androgen-independent metastatic cells, such as PC-3. In this report, we show IL-8 functions androgen independence, chemoresistance, tumor growth, angiogenesis. We stably transfected LAPC-4 with cDNA selected IL-8–secreting (IL8-S) transfectants. IL8-S transfectants that secreted at levels similar to by PC-3 (100–170 ng/106...

Magnetic nanofibrous scaffolds of poly(caprolactone) (PCL) incorporating magnetic nanoparticles (MNP) were produced, and their effects on physico-chemical, mechanical biological properties extensively addressed to find efficacy for bone regeneration purpose. MNPs 12 nm in diameter citrated evenly distributed PCL solutions up 20% then electrospun into nonwoven webs. Incorporation greatly improved the hydrophilicity nanofibers. Tensile nanofibers (tensile strength, yield elastic modulus...

The proinflammatory chemokine receptor CXCR7 that binds the ligands CXCL11 and CXCL12 (SDF-1a) is elevated in a variety of human cancers, but its functions are not understood as it does elicit classical signaling. Here we report procancerous cytokine IL-8 (interleukin-8) upregulates expression along with ligand-independent promote growth proliferation prostate cancer cells (CaP cells). In cell culture, ectopic or addition selectively increased at level mRNA protein production. Conversely,...

Theranostics based on nanoparticles (NPs) is a promising paradigm in nanomedicine. Mesoporous silica nanoparticle (MSN)-based systems offer unique characteristics to enable multimodal imaging or simultaneous diagnosis and therapy. They include large surface area volume, tunable pore size, functionalizable surface, acceptable biological safety. Hybridization with other NPs chemical modification can further potentiate the multifunctionality of MSN-based toward translation. Here, we update...

Here we communicate the development of a novel multifunctional hybrid nanomaterial, magnetic carbon nanotubes (CNTs) ensheathed with mesoporous silica, for simultaneous applications drug delivery and imaging. Magnetic nanoparticles (MNPs) were first decorated onto multiwalled CNTs, which was then layered silica (mSiO2) to facilitate loading bioactive molecules large quantity while exerting properties. The nanomaterial showed high mesoporosity due surface-layered mSiO2, excellent properties,...

Abstract Magnetic nanoparticles (MNPs) are considered highly useful in therapeutic and diagnostic applications. However, MNPs require surface modification to promote dispersibility aqueous solutions thus biocompatibility. In this article, the authors modified with inorganic silica layer create silica‐coated magnetite (MNP@Si) via sol–gel process. Synthesis involves hydrolysis condensation steps using tetraethylorthosilicate (TEOS) methanol/ polyethylene glycol (PEG) solution ammonia...
