Our Science

CycloPure is commercializing the pioneering polymer technologies discovered by the Dichtel Lab.  Using these technologies, the company has developed a new class of highly-adsorbent materials that separate and remove pollutants, VOCs and other organic compounds from water and air.

Highly Adsorbent Cyclodextrin Networks

Combining cyclodextrin with specific, rigid monomers into repeating structures  creates a  polymer network of high surface area pores  with precise adsorption properties.

High Surface Area

CycloPure’s polymers derive  their effectiveness by  linking cup-shaped cyclodextrin building blocks into porous, high surface area structures.

Adsorption by Encapsulation

The pores form  high-affinity pockets into which contaminants are  drawn and trapped, making the polymers ideally  suited for separation and removal of unwanted  compounds from water and air.

Designing Affinity

By varying the molecular  building blocks, the polymer can be altered into
different formulations tailored to the chemical  properties of target contaminants.

Rapid Uptake at Low Concentration​s

Because of their porous surface area and high-affinity pockets, the polymers are able to bind and rapi dly adsorb  pollutants at low concentration. This is important as many contaminants retain potency and toxicity at very low  concentration. This highly efficient adsorption process  allows water treatment in constant flow installations.

As published in Nature (January 14, 2016),  porous  cyclodextrin polymers (P-CDP)  achieved  95% adsorption of bisphenol A, a  component of plastics (BPA), in  10 seconds.

​Norit AC (NAC),  the next leading  adsorbent, achieved contaminant  removal in 10 minutes, and only   adsorbed 53% of the pollutant in 10  seconds.

Sustainably made with favorable life-cycle characteristics

Favorable Life-Cycle 

The company’s science is performed in a material that is sustainable and has environmentally friendly life-cycle characteristics.

Renewable Source

​The polymers are formed in a single-step reaction using cyclodextrin, a compound made from corn starch.

Easy Regeneration

​When fully adsorbed, the material can easily be regenerated through a simple rinsing.
