Matthew R. Linford (born April 9, 1966) [1] is an associate professor at Brigham Young University, Department of Chemistry and Biochemistry (Provo, Utah) since September 2006. His lab is devoted to synthesizing hydrophobic surfaces, diamond stationary phases for liquid chromatography and microfabricated TLC plates.
Linford works in surface modification and characterization, particularly in studying organic thin films (monolayer and polymer), modifying silicon, diamond, silicon oxide, gold, and polymers, surface patterning, and organic chemistry. He also works with thin-film deposition using silanes, alkenes, thiols, and treats by sputtering. [2] In his group, they also undertake liquid chromatography (HPLC and TLC) and solid phase extraction (SPE), develop hydrophobic coatings for various materials. They study materials for optical data storage, and perform surface analysis by XPS, ToF-SIMS, wetting, optical ellipsometry, and FTIR. His lab also performs chemometrics of mass spectroscopic data (PCA, MCR, cluster analysis, and PRE). [3]
Linford received his Bachelor of Science in Chemistry from Brigham Young University in September 1990, followed by a Master of Science in Materials Science and Engineering and a PhD in Chemistry from Stanford University later in June 1996. He served as a post-doctoral fellow at the Max Planck Institute for Colloid and Surface Sciences from July 1996 to June 1997. [4]
Linford has worked on topics including supercritical fluid chromatography and the formation of the first alkyl monolayers on silicon using diacyl peroxides. He has studied the use of synchrotron radiation to characterize monolayers on silicon, worked on the gas-phase free-radical modification of alkyl monolayers, devised a new method for coating particles, and studied the strong effect of ionic strength on surface dye extraction during dye-polymer multilayer formation. He has worked on growing semiconducting particles in polyelectrolyte multilayers, designed a cell to study the flow-induced orientation of polyelectrolytes on surfaces, described a mixing process using matrix algebra, also he synthesized and characterized films of new polyelectrolytes.[ citation needed ]
Linford served for a few years in the industrial sector. While working as a senior scientist at Rohm and Haas Company, he developed an IR tool for the rapid screening of catalysts, and he designed and built a laser scanner for detecting defects on plastic sheets which can be used as a substrate for flat panel liquid crystal displays. He has worked as a senior scientist/consultant for Praelux, Inc. and developed methods to immobilize single nucleotides and DNA oligomers onto surfaces. He developed procedures to attach a nickel (NTA) chelator to glass coverslips to bind proteins with 6-his tags, developed novel methods to immobilize amines onto surfaces, performed surface patterning using microcontact printing, and worked on bioconjugation of a protein to glass microspheres.[ citation needed ]
Linford has served as a director of research for Nano-Tex, LLC. and developed the product "Nano-Dry" to make nylon and polyester hydrophilic. This product increases the comfort of fabrics, and it is currently being marketed throughout the United States. (Tiger Woods is shown in the October 2003 issue of Golf Digest is wearing a pair of pants that have this finish on them – Nano-Dry had become part of the Nike golf collection. He has been an inventor on 10 patents from work with Nano-Tex. He designed and synthesized numerous polymers (mostly free radical polymerizations of acrylates and methacrylates). He also formulated polymers, surfactants, wetting agents and defoaming agents.[ citation needed ]

A monolayer is a single, closely packed layer of entities, commonly atoms or molecules. Monolayers can also be made out of cells. Self-assembled monolayers form spontaneously on surfaces. Monolayers of layered crystals like graphene and molybdenum disulfide are generally called 2D materials.
Molecular engineering is an emerging field of study concerned with the design and testing of molecular properties, behavior and interactions in order to assemble better materials, systems, and processes for specific functions. This approach, in which observable properties of a macroscopic system are influenced by direct alteration of a molecular structure, falls into the broader category of “bottom-up” design.
Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, is a silicone polymer with a wide variety of uses, from cosmetics to industrial lubrication and passive daytime radiative cooling.
An artificial membrane, or synthetic membrane, is a synthetically created membrane which is usually intended for separation purposes in laboratory or in industry. Synthetic membranes have been successfully used for small and large-scale industrial processes since the middle of the twentieth century. A wide variety of synthetic membranes is known. They can be produced from organic materials such as polymers and liquids, as well as inorganic materials. Most commercially utilized synthetic membranes in industry are made of polymeric structures. They can be classified based on their surface chemistry, bulk structure, morphology, and production method. The chemical and physical properties of synthetic membranes and separated particles as well as separation driving force define a particular membrane separation process. The most commonly used driving forces of a membrane process in industry are pressure and concentration gradient. The respective membrane process is therefore known as filtration. Synthetic membranes utilized in a separation process can be of different geometry and flow configurations. They can also be categorized based on their application and separation regime. The best known synthetic membrane separation processes include water purification, reverse osmosis, dehydrogenation of natural gas, removal of cell particles by microfiltration and ultrafiltration, removal of microorganisms from dairy products, and dialysis.
The contact angle is the angle between a liquid surface and a solid surface where they meet. More specifically, it is the angle between the surface tangent on the liquid–vapor interface and the tangent on the solid–liquid interface at their intersection. It quantifies the wettability of a solid surface by a liquid via the Young equation.

Layer-by-layer (LbL) deposition is a thin film fabrication technique. The films are formed by depositing alternating layers of oppositely charged materials with wash steps in between. This can be accomplished by using various techniques such as immersion, spin, spray, electromagnetism, or fluidics.
Graphite oxide (GO), formerly called graphitic oxide or graphitic acid, is a compound of carbon, oxygen, and hydrogen in variable ratios, obtained by treating graphite with strong oxidizers and acids for resolving of extra metals. The maximally oxidized bulk product is a yellow solid with C:O ratio between 2.1 and 2.9, that retains the layer structure of graphite but with a much larger and irregular spacing.
Hydrophobic silica is a form of silicon dioxide that has hydrophobic groups chemically bonded to the surface. The hydrophobic groups are normally alkyl or polydimethylsiloxane chains. Hydrophobic silica can be processed in different ways; such as fumed silica, precipitated silica, and aerosol assisted self assembly, all existing in the form of nanoparticles.
Institut Charles Sadron is a research center of the Centre national de la recherche scientifique, associated with the University of Strasbourg, which was created in 1954 to answer the demand for fundamental research in the emerging field of polymer science.
Surface-assisted laser desorption/ionization (SALDI) is a soft laser desorption technique used for mass spectrometry analysis of biomolecules, polymers, and small organic molecules. In its first embodiment Koichi Tanaka used a cobalt/glycerol liquid matrix and subsequent applications included a graphite/glycerol liquid matrix as well as a solid surface of porous silicon. The porous silicon represents the first matrix-free SALDI surface analysis allowing for facile detection of intact molecular ions, these porous silicon surfaces also facilitated the analysis of small molecules at the yoctomole level. At present laser desorption/ionization methods using other inorganic matrices such as nanomaterials are often regarded as SALDI variants. As an example, silicon nanowires as well as Titania nanotube arrays (NTA) have been used as substrates to detect small molecules. SALDI is used to detect proteins and protein-protein complexes. A related method named "ambient SALDI" - which is a combination of conventional SALDI with ambient mass spectrometry incorporating the direct analysis real time (DART) ion source has also been demonstrated. SALDI is considered one of the most important techniques in MS and has many applications.

Nanoclusters are atomically precise, crystalline materials most often existing on the 0-2 nanometer scale. They are often considered kinetically stable intermediates that form during the synthesis of comparatively larger materials such as semiconductor and metallic nanocrystals. The majority of research conducted to study nanoclusters has focused on characterizing their crystal structures and understanding their role in the nucleation and growth mechanisms of larger materials.
A rapidly increasing list of graphene production techniques have been developed to enable graphene's use in commercial applications.
Gero Decher is a German chemist and Distinguished Professor at the Faculty of Chemistry of University of Strasbourg. He is best known for his seminal role in the development of polyelectrolyte multilayers, which is today known as “layer-by-layer (LbL) assembly”, a simple yet powerful nanofabrication method that has enabled the development of entirely new technologies, such as biocompatible coatings on medical devices, ultrastrong nanocomposites, neural interfaces, charge-storage devices, gas separation, fire retardants, and gene delivery platforms. According to CNRS International Magazine, Decher's work has “sparked a small revolution in materials science”. Layer-by-layer assembly is now an established part of the nanobiotechnology curriculum.
