The closure of gaps within epithelia is crucial to maintain its integrity during biological processes such as wound healing and gastrulation. Depending on the distribution of extracellular matrix, gap closure occurs through assembly of multicellular actin-based contractile cables or protrusive

The restriction endonuclease EcoRV can rapidly locate a short recognition site within long non-cognate DNA using 'facilitated diffusion'. This process has long been attributed to a sliding mechanism, in which the enzyme first binds to the DNA via nonspecific interaction

We prepared novel Fe(3)O(4) magnetic nanoparticles (MNPs) modified with 3-aminopropyltriethoxysilane (APS) and copolymers of acrylic acid (AA) and crotonic acid (CA). The MNPs were characterized by transmission electron microscopy, X-ray diffraction, infra-red spectra and thermogravimetric analysis. We explored the ability

Questions

1–3 of 3 Questions  

  1. Hello. I noticed this special packaging of APTES for deposition: 706493-20ML. Can you tell me more? We have a Yield Engineering Systems oven. Is this packaging for that oven?

    1 answer

    1. This product is packaged for use in deposition systems. The Yield Engineering Systems (YES) CVD (Chemical Vapor Deposition) equipment can precisely control deposition parameters such as the reactant volume, reaction temperature, and deposition time, which are ideal for APTES deposition. Although bulky and expensive, the system makes the deposition process is relatively simple. The oxide surface can be hydroxylated with plasma using the YES system or a piranha solution, beforehand. The APTES is stored in temperature-controlled flasks where it is evaporated and introduced to the deposition chamber, which is kept at 150 °C and a low pressure (0.5-500 Torr). Nitrogen purges have been used before the deposition to dehydrate the surface or after deposition to remove physisorbed molecules. Rather than dehydrate the surface, water vapor can also be introduced to hydrate it, if so desired. The deposition time using a YES system is short compared to other methods. In the literature, YES CVD systems have been used to deposit monolayers of APTES using processes with different steps.
