Product Advantages

Features

30 minute stabilization time : The Gluco-ChaserTM CGM sensor reduces initial stabilization to only 30 minutes upon sensor installment by using proprietary technology. This stabilization time stands as the shortest among current commercial CGMs, and this drastic time reduction is achieved through (1) simplifying an otherwise inefficient sensor installment procedure; (2) allowing users flexibility in how frequently the sensors are replaced -- made possible by the highly affordable Gluco-ChaserTM sensor.

Elimination of major interferents : The proprietary polymer membrane can preclude major well- known interferents such as acetaminophen and maltose that work against glucose sensors.

Calibration-free : This sensor remains stable for five days without calibration. Additionally, the sensor only requires factory calibration, unlike many CGMs which require finger-prick sensors for calibration.

Highly-competitive pricing : Unlike traditional glucose biosensors, Gluco-ChaserTM does not need a glucose-reactive enzyme, which is unstable and expensive. Our technology uses chemically and mechanically robust colloidal metal particles for signal transduction. This technology drastically lowers the manufacturing cost of the electrode, a key sensing component of the product.

Business Benefits

(1) Unlike most glucose sensors, Gluco-ChaserTM does not require an unstable and expensive enzyme for glucose detection.

(2) This leads to huge cost savings in production and storage of the core sensing components.

(3) Gluco-ChaserTM technology is applicable to various formats of glucose monitors from conventional BGM to short-term (8 ~ 48 hours) and long-term (3 ~ 7 days, and beyond) CGMs.

Usage Benefits

(1) Calibration-free operation of the sensor

(2) 30-Minute window for initial stabilization (competitors range anywhere from 3 to 12 hrs)

(3) Affordable pricing, comparable to that of conventional finger-prick sensors

This package of features has yet to be implemented by current market leaders, making the Gluco-ChaserTM CGM a smarter choice for Type-2 as well as Type-1 patients.

FAQs

How innovative is the Gluco-ChaserTM platform as a glucometer?

The founders of Gluco-Chaser Inc discovered in 2003 and 2004* that an aggregate of colloidal platinum particles are capable of detecting glucose on an electrode. They also showed that the platinum aggregate is a superior alternative to glucose-reactive enzymes used by current glucose biosensors, which fall short in in terms of the stability and the cost.
Every aspect of Gluco-ChaserTM technology is proprietary, including the processing of colloidal particles, the glucose detection scheme, and a variety of polymer coatings. Gluco-ChaserTM is a highly reliable platform offered at a remarkably affordable price-features that make it a potential primary leader in the glucose monitor market.

What are the advantages of Gluco-ChaserTM non-enzymatic electrochemical glucose sensor?

The advantages of Gluco-ChaserTM non-enzymatic electrochemical glucose sensor include: (1) the reliability of the sensor’s performance; (2) the low cost in production and long-term storage under temperature conditions harmful to enzymes, enabling affordable end user pricing; (3) short initiation time.

* 30 minutes taken compared with 3~12 hours of major market leaders.

What is the working principle of Gluco-ChaserTM non-enzymatic electrochemical glucose sensor?

An aggregate of colloidal platinum particles is loaded onto a printed electrode. The colloidal platinum particles oxidize glucose upon application of an electric potential, which then generates the electrical signal corresponding to the amount of glucose. This working principle of Gluco-ChaserTM sensor is an alternative to current glucose biosensors, most of which operate by immobilizing an expensive and hard-to-control glucose-responsive enzyme on an electrode.

Is the electrode preparation process for Gluco-ChaserTM manufacture compatible?

Yes, it can be manufacture-compatible. First, it is possible to scale up the processing  of colloidal particles. Also, it is also possible to load an aggregate of colloidal particles onto a patterned electrode in a reproducible manner at a high throughput.

What are other features unique to Gluco-ChaserTM technologies?

The sensor offers (1) calibration-free operation of the sensor*; (2) 30-minute window for initial stabilization (competitors range anywhere from 3 to 12 hrs); and (3) affordable pricing, comparable to that of conventional finger-prick sensors. This package of features has yet to be implemented by current market leaders, making the Gluco-ChaserTM CGM a smarter choice for Type-2 as well as Type-1 patients.
 
* Currently under development.

How frequently is the proposed non-enzymatic electrochemical glucose sensor replaced?

Gluco-ChaserTM CGM will offer two replacement interval options: short-term (1~2 days) and long-term (> 3 days). The short-term sensor replacement is made possible by the low cost and the Gluco-ChaserTM technology, drastically reducing the initiation time. As a result, user comfort level and hygiene are improved. As for the long-term interval option, Gluco-ChaserTM technology is currently comparable to that of major market leaders. However, development is underway to upgrade existing polymer coating to extend the operational life to as long as possible. In fact, Gluco-ChaserTM CGM sensor was operational without signal deterioration for one month while being immersed in human whole blood and human plasma.

How can you detect glucose from biofluids without use of an enzyme specifically reactive to glucose?

Currently, the Gluco-ChaserTM system is highly specific to glucose contained in body fluids. The system has been engineered in such a way that it can preclude the signals originating from major interferents (e.g. ascorbic acid, acetaminophen, and maltose) contained in body fluids.

What are the advantages of CGM over disposable finger-prick BGMs?

Real time monitoring of a glucose change is considered ideal for identification and management of diabetes. In this regard, CGM (Continuous Glucose Monitor) is much better at (1) judging whether one has diabetes; (2) identifying the pattern of the glucose change for timely insulin dose feed.

Is it possible to use a CGM (Continuous Glucose Monitor) for the management of type-2 diabetes? What are the pros and cons of doing so?

CGMs are generally known to be better for the management of type-1 diabetes, for which accurate insulin feed in response to glucose level change is imperative. Ideally the same criteria can be applied to the case of type-2 diabetes. However, many patients who are suffering from a less severe form of type-2 diabetes are likely to find it very cumbersome and costly to use current CGMs available in the market. Current CGMs are very uncomfortable to use, usually requiring 3~12 hours of installation in addition to wearing for longer than 5 days. Therefore, the CGM sensor system and its disposables may be too costly for these type-2 diabetics.

What is the developmental status of Gluco-ChaserTM CGM?

We have developed a prototype CGM, whose animal model glucose level results show an excellent match with those of a leading commercial finger-prick BGM sensor.

Why Gluco-Chaser CGMTM?

The onset of type-2 diabetes is hard to identify, and more than 40 % of type-2 patients are unaware of disease onset. Currently, identification of onset using commercial glucose monitors is difficult due to high costs and lack of user comfort. The Gluco-ChaserTM CGM is low-cost and easy-to-use, allowing users to evaluate their status quickly.  Our CGM is also the first ever in the market to provide quick installation as well as short-term replacement of sensor patches (See #6)

Why do you prioritize CGM over the BGM, even though the market size for the BGM is much bigger?

We are focusing more on Gluco-ChaserTM CGM simply because (1) Gluco-ChaserTM is able to address the huge, but unaddressed market to identify new type-2 patients; (2) there is a clear market trend that CGM, capable of real time monitoring, attempts to undertake the type 2 BGM market as an ideal form of glucose monitoring; (3) Gluco-ChaserTM technology has advantageous solutions to overcome the obstacles to such a shift in terms of the ease-of-use and the cost.

As of the current stage of development, however, it would take less cost and time to pursue commercialization of Gluco-ChaserTM BGM. Therefore, we are open to discussing such an opportunity regarding the Gluco-ChaserTM BGM.
