A general concept for parallel near-field photochemical and radiation-induced chemical processes for the fabrication of nanopatterns of a self-assembled monolayer (SAM) of (3-aminopropyl)triethoxysilane (APTES) is explored with three different processes: 1) a near-field photochemical process by photochemical bleaching of a monomolecular layer of dye molecules chemically bound to an APTES SAM, 2...

Robotic microhandling is a promising way to assemble microcomponents in order to manufacture a new generation of hybrid microelectromechanical systems. However, at the scale of several micrometers, the adhesion phenomenon highly perturbs the micro-object release and positioning. This phenomenon is directly linked to both the object and the gripper surface chemical composition. We propose to con...

BACKGROUND Mesoporous silica nanoparticles (MSNs) have several attractive properties as a drug delivery system, such as ordered porous structure, large surface area, controllable particle size as well as interior and exterior dual-functional surfaces. The purpose of this study was to develop novel lactosaminated mesoporous silica nanoparticles (Lac-MSNs) for asialoglycoprotein receptor (ASGPR) ...

Abstract Soybean hulls (SBHs) are one of the main by-products soybean crushing, usually destined for animal feeding or to become a putrescible waste. In this work, we upgraded SBHs materials with antimicrobial properties. After extraction peroxidase from SBHs, an enzyme applicable in different technological sectors and naturally present hulls, exhausted biomass was subjected acid–base treatment...

Water pollution caused by heavy metal ions has attracted worldwide attention. In this work, gold tailings were used as raw materials and the sol–gel method combined with atmospheric pressure drying to achieve low-cost preparation of a silica aerogel. (3-Aminopropyl) triethoxysilane (APTES), ethylenediaminetetraacetic acid disodium salt (EDTA-2Na), chitosan modify aerogel, which was then an adso...

New potential High Voltage Direct Current (HVDC) cable insulation materials based on nanocomposites are developed in this study. The produced by blending of polypropylene (PP), propylene-ethylene copolymer (PP–HI) and a modified fumed silica (A-silica) concentration 1 2 wt %. A-silica is successfully with (3-aminopropyl)triethoxysilane (APTES) via solvent-free method, as proven infrared spectro...

The precise and rapid detection of hazardous molecules, microorganisms, pollutants, toxins currently remains a global challenge. Aflatoxin B1 (AFB1) is toxic dangerous product fungi that considered as cancerogenic, mutagenic, immunosuppressive for humans animals. Therefore, the screening AFB1 in food beverages plays an important role preventing foodborne illnesses. In this study, molecules were...

Peptide nucleic acids (PNA) are a unique class of synthetic molecules that have a peptide backbone and can hybridize with nucleic acids. Here, a versatile method has been developed for the automated, in situ synthesis of PNA from a porous silicon (PSi) substrate for applications in gene therapy and biosensing. Nondestructive optical measurements were performed to monitor single base additions o...

This paper reports a versatile and irreversible bonding method for poly(dimethylsiloxane) (PDMS) and SU-8. The method is based on epoxide opening and dehydration reactions between surface-modified PDMS and SU-8. A PDMS replica is first activated via the low-cost lab equipment, i.e., the oxygen plasma cleaner or the corona treater. Then both SU-8 and plasma-treated PDMS samples are functionalize...
