We present an investigation of multiple droplet growth dynamics on homogeneous and patterned surfaces during dropwise condensation. Our analysis is based three-dimensional thermal lattice Boltzmann simulations. First, we investigate the surfaces. The droplets a surface shows that lower static contact angle surface, higher condensed volume liquid. After that, discuss (a with hydrophilic hydropho...

The surface physicochemical properties of Listeria monocytogenes LO28 under different conditions (temperature and growth phase) were determined by use of microelectrophoresis and microbial adhesion to solvents. The effect of these parameters on adhesion and biofilm formation by L. monocytogenes LO28 on hydrophilic (stainless steel) and hydrophobic (polytetrafluoroethylene [PTFE]) surfaces was a...

As encapsulation of hydrophilic drugs in the solid lipid nanoparticles (SLNs) is still a challenging issue, the aim of this study was to prepare SLNs containing tramadol hydrochloride as a hydrophilic compound.The SLNs were prepared using glycerol monostearate (GMS), soy lecithin and tween 80 by double emulsification-solvent evaporation technique. The nanoparticles were optimized through a cent...

The present work aims to improve the sensitivity of an electrical biosensor by simply changing a surface property of the passivation layer, which covers the background region except for the sensing site for electrical isolation among adjacent interconnection lines. The hydrophobic passivation layer dramatically enhances the sensitivity of the biosensor when compared with a hydrophilic passivati...

The adhesion of Escherichia coli, Pseudomonas putida and Acinetobacter calcoaceticus cells to MicrodynNadir ultrafiltration membranes of various chemical nature: PS100 (polysulfone), P005 (polyethersulfone), C100 (regenerated cellulose) was studied. It was shown that an adhesiveness of the microorganisms to the membranes essentially depends on hydrophobic/hydrophilic properties of both the cell...

PURPOSE To compare the ongrowth of lens epithelial cells (LECs) on the anterior surface of 6 different hydrophilic intraocular lenses (IOLs). SETTING Medical University of Vienna, Department of Ophthalmology and Optometry, Vienna, Austria. METHODS Six models of hydrophilic IOLs were compared in this prospective study: Visionflex A-100 (Distra Softcryl), Rayner Centerflex 570H (Rayner), Coll...

Appropriate surface wettability and roughness of biomaterials is an important factor in cell attachment and proliferation. In this study, we investigated the correlation between surface wettability and roughness, and biological response in human adipose-derived stem cells (hADSCs). We prepared wettable and rough gradient polyethylene (PE) surfaces by increasing the power of a radio frequency co...

Inspired by the lotus effect in nature, surface roughness engineering has led to novel materials and applications in many fields. Despite the rapid progress in superhydrophobic and superoleophobic materials, this concept of Mother Nature's choice is yet to be applied in the design of advanced nanocarriers for drug delivery. Pioneering work has emerged in the development of nanoparticles with ro...

This study describes the identification of aqueous-soluble antigens in Leishmania promastigotes immunologically and biochemically closely related to the major surface antigen. Proteins from surface-iodinated L. braziliensis braziliensis and L. donovani chagasì promastigotes, extracted and separated by partitioning in the detergent Triton X-114, were analyzed. Immunoblotting of the extracted pro...
