08-26-2021-1541 - Nanoreactors

Nanoreactors are a form of chemical reactor that are particularly in the disciplines of nanotechnology and nanobiotechnology. These special reactors are crucial in maintaining a working nanofoundry; which is essentially a foundry that manufactures products on a nanotechnological scale.

 

General information[edit]

Researchers in the Netherlands have succeeded in building nanoreactors that can perform one-pot multistep reactions - the next step towards artificial cell-like devices in addition for applications involving the screening and diagnosis of a disease or illness.[1] A biochemical nanoreactor is created simply by unwrapping a biological virus through scientific methods, eliminating its harmful contents, and re-assembling its protein coat around a single molecule of enzyme.[2] The kinetic isotope effect is trapped in a single molecule within a membrane-based nanoreactor.[3] This is a phenomenon that has been found by researchers in the United Kingdom during experiments done in September 2010.[3] The kinetic isotope effect, where the rate of a reaction is influenced by the presence of an isotopic atom in solution, is an important principle for elucidating reaction mechanisms.[3] This recent finding could open up new methods to study chemical reactions.[3] They may even aid in the process of creating new (and even more powerful) nanoreactors.[3]

Using nanocrystals, a scalable and inexpensive process can ultimately create nanoreactors.[4] Researchers at the Lawrence Berkeley National Laboratory in Berkeley have the ability to take advantage of the large difference in select components to create these nanocrystals and nanoreactors.[4] Nanocrystals are easier to use and less expensive than methods that employ sacrificial templates in the creation process of hollow particles.[4] Catalyst particles are separated into shells in order to prevent particle aggregation.[4] Selective entry into the catalysis chamber reduces the likelihood of desired products undergoing secondary reactions.[4]

Nanoreactors can also be built by controlling the positioning of two different enzymes in the central water reservoir or the plastic membrane of synthetic nanoscopic bubbles.[5] Once the third enzyme is added into the surrounding solution, it becomes possible for three different enzymatic reactions to occur at once without interfering with each other (resulting in a "one-pot" reaction).[5] The potential for nanoreactors can be demonstrated by binding the enzyme horseradish peroxidase into the membrane itself; trapping the enzyme glucose oxidase.[5] The surrounding solution would end up containing the enzyme lipase B with the glucose molecules containing four acetyl groups as the substrate.[5] The resulting glucose would cross the membrane, become oxidized, and the horseradish peroxidase would convert the sample substrate ABTS (2,2’-azinobis(3-ethylbenzthiazoline-6-sulfonic acid)) into its radical cation.[5]

Abilities[edit]

Nanoreactors can also be used to emulsify water, create hydrofuels (which essentially blends 15% water into the refined diesel product), play a helpful role in the chemicalindustry by allowing multiple streams of raw materials to exists in a single nanoreactor, manufacture personal care products (i.e., lotionspharmaceutical creamsshampoosconditionersshower gelsdeodorants), and improve the food and beverage industries (by processing saucespuréescooking bases for soup, emulsifying non-alcoholic beverages, and salad dressings).[6]

Personal care goods can be enhanced by companies feeding multiple phases of material, using a mixing device with water, and creating instant emulsions.[6] These emulsions would come with smaller particles, are expected to have a longer shelf life and an give off an enhanced appearance when sold at retailers.[6] The needs of the food and beverage industry can result in lower processing costs, more space, better efficiency, and lower equipment costs.[6] This may bring down the cost of food and beverages for consumers; even alcoholic beverages that are subject to hidden sin taxes.

Hydrofuel can be used to move heavy duty transportstrains, earth-moving equipment (including bulldozers), in addition to providing fuel to most boats and ships.[6]Reduced pollution and increased fuel efficiency may come out of nanoreactor-produced hydrofuel.[6] The increased usage of renewable energy may also help to improve the world's environment thanks to nanoreactors.[6]
