Glucose Biosensors Industry: Advances in Glucose Biosensor Technology Revolutionizing Healthcare Industry

Rise
of Non-Invasive Glucose Biosensors Industry
The traditional method of glucose monitoring requiring blood samples is being
rapidly replaced by non-invasive glucose monitoring technology. Various
companies are developing glucose biosensors that can painlessly and
continuously monitor glucose levels in interstitial fluid or other body fluids
without requiring frequent blood pricking. Notable among these are continuous
glucose monitors (CGMs) that use interstitial fluid or other body fluids to
measure glucose levels. CGMs eliminate the need for frequent finger pricking
while providing real-time glucose readings through the day and night. This
brings more convenience to diabetics and helps achieve better glycemic control.
Advancements in CGM Sensing Technology
To make CGMs reliable, accurate and user-friendly, companies are worked on
advancing the sensing components. Global
Glucose Biosensors Alternatives to
enzyme-based electrochemical sensing are being explored. Masimo with its latest
CGM, Guardian Sensor, uses a miniaturized optical fluorescent sensor that
tracks glucose levels from interstitial fluid. Dexcom with its G6 CGM has also
moved from enzyme-based to enzyme-free sensing which is helping to improve
accuracy and extend sensor life to up to 10 days. Senseonics has developed an
implantable Eversense CGM using fluorescence sensing which can continuously
track glucose for up to 6 months from within the body. Advancements in sensor
materials, miniaturization of components and sensor calibration algorithms are
further enhancing CGM performance.
Transition to Factory Calibration
Historically, users of CGMs had to perform finger prick calibrations multiple
times daily to ensure the CGM readings matched the blood glucose readings. This
defeated the purpose of painless monitoring. Now, next-gen CGMs are
transitioning to factory calibration where the sensors are calibrated in the
manufacturing facility before being inserted. This eliminates the need for
self-calibration finger pricks. Dexcom’s G6 was the first CGM to implement
factory calibration. Senseonics’ Eversense also employs factory calibration.
Factory calibration delivers calibration accuracy without user intervention,
improving usability and eliminating some pain points of earlier CGMs.
Integration with Automated Insulin Delivery Systems
The highly accurate and reliable data from next-gen CGMs is enabling
integration with automated insulin delivery (AID) systems which can help
achieve tight glycemic control automatically. Notable examples are Tandem
Diabetes’ Control-IQ hybrid closed loop system which integrates with Dexcom G6
CGM and Medtronic’s MiniMed 780G hybrid closed loop system integrated with
Guardian CGM. Such integrated systems can basal bolus deliver insulin
continuously based on CGM glucose readings without user intervention, helping
reduce glycemic variations especially at night. This brings diabetes management
a step closer to artificial pancreas solutions. More advanced AID systems
relying solely on CGM data without user actions are being targeted by
companies.
Growing Glucose Biosensors Industry
The advancements and improved usability of new generation CGMs is driving
strong adoption globally. According to a recent report, the global glucose
biosensor market valued at $15.9 billion in 2020 and is estimated to grow at an
annual rate of 6.9% to reach $26.4 billion by 2028. North America accounts for
the largest share currently due to high diabetes prevalence and stringent
national diabetes treatment guidelines supporting CGM reimbursement.
In
Summary, the Asia Pacific region is witnessing fastest growth rate driven by
growing diabetes burden in major countries, increasing healthcare expenditure
and favorable insurance coverage for diabetes management devices. As sensing
and automation technologies further progress, the glucose biosensor market will
continue maintaining double-digit growth rate through next decade, transforming
diabetes management modalities worldwide.
