Antibiotics were once the golden bullet to constrain infectious bacteria. However, the rapid and continuing emergence of antibiotic resistance (AR) among infectious microbial pathogens has questioned the future utility of antibiotics. This dilemma has recently fueled the marriage of the disparate fields of nanochemistry and antibiotics. Nanoparticles and other types of nanomaterials have been extensively developed for drug delivery to eukaryotic cells. However, bacteria have very different cellular architectures than eukaryotic cells.This review addresses the chemistry of nanoparticle-based antibiotic carriers, and how their technical capabilities are now being re-engineered to attack, kill, but also non-lethally manipulate the physiologies of bacteria. This review also discusses the surface functionalization of inorganic nanoparticles with small ligand molecules, polymers, and charged moieties to achieve drug loading and controllable release.

“…This concept of separating nanoparticle synthesis and nanocomposite formation has been previously demonstrated to produce nanocomposites with organic matrices [43][44][45] , oxide matrices 46, 47 and semiconductor matrices. [48][49][50] Herein, we have applied this concept to metal matrix nanocomposites. We do note that identifying appropriate metal precursors is not trivial because many precursors decompose into metal-oxide instead of metal.…”

Abstract:Phase change materials (PCMs) are of broad interest for thermal storage and management applications. For energy dense storage with fast thermal charging/discharging rates, a PCM should have a suitable melting temperature, large enthalpy of fusion, and high thermal conductivity. To simultaneously accomplish these traits, we custom design nanocomposites consisting of phase change Bi nanoparticles embedded in an Ag matrix. We precisely control nanoparticle size, shape, and volume fraction in the composite by separating the nanoparticle

“…In order to use the nanocrystals for these applications, size and shape control of the nanocrystals and development of "bottom-up" process are most important. 4,5 However, there have been only a few reports on dielectric and ferroelectric nanocubes and their potential applications so far. Barium titanate (BT) and strontium titanate (ST) are the most popular perovskite oxides for electronic device application such as multilayered ceramic capacitor (MLCC), positive temperature coefficient (PTC) thermistor, and so on.…”

Orderly assemblies of BaTiO3 (BT) nanocubes, SrTiO3 (ST) nanocubes and BT-ST mixture nanocubes were fabricated on Pt-coated Si substrate directly by solution self-assembly and heated at 850 °C. The dielectric nanocubes aligned face to face in a quite wide region of several tens of square-micrometers with a height of one micrometer, and even inside of the structures was ordered. The piezoresponse of BT-ST mixture assembly showed non-linear curve and stepwise behavior at high poling field, which differed from ferroelectric BT and paraelectric ST nanocube assemblies.
