NEC announced the successful development of artificial DNA aptamers (*1) that bind to the novel coronavirus (SARS-CoV-2). This breakthrough stems from the NEC Group’s efforts to promote spatial monitoring business using aptamers, including the development of new biosensing systems, such as measuring equipment that can monitor spaces where various viruses, including SARS-CoV-2 and influenza viruses, are present.
NEC uses NANOSENSORS™ Membrane Surface Stress Sensors (MSS) in the development of a measuring device that enables spatial monitoring of SARS-CoV-2.
The video on NANOSENSORS™ Membrane-type Surface-stress Sensors (MSS) for olfactory sensing has passed the 2000 views mark. Thank you all for watching.
The NANOSENSORS™ Membrane-type Surface-stress Sensor – MSS is a non-packaged MEMS sensor, a silicon membrane platform supported with four beams on which piezoresistors are embedded. It is mainly dedicated to R&D in the areas of olfactory sensing and electronic noses but some types can also be used for static/pulsed-field torque magnetometry and force sensing.
The MSS offered by NANOSENSORS via the Special Developments List are raw sensor platforms intended to provide researchers with a platform for their research so that they don’t have to start their setup from scratch. The MSS sensors will still need to be coated with detection layers developed and applied by the individual researchers in order to become functional sensors.
There are currently two major applications for this type of sensor:
the MSS has a great potential as a core component for electronic (artificial) nose systems / olfactory sensing systems utilized in e.g. food, environment, safety and security and medical ( e.g. human breath analysis ) fields. NANOSENSORS offers two types of MSS sensors for this application.: SD-MSS-1K2G and SD-MSS-1K2GP. The recently introduced SD-MSS-1K2GP can also be employed for “liquid” or “wet” applications thereby extending the potential use of MSS sensors to R&D in the sensing of taste, detections of chemical reactions in solutions, etc.
the MSS can also be used for assessment of various materials like organic conductors, magnetic and superconductor materials in torque magnetometry. NANOSENSORS currently offers three MSS sensors which can be used for this type of application: SD-MSS-1KTM, SD-MSS-1KPMAl and SD-MSS-1KPMAu.
On these pages you will not only get more information on which types of MSS Sensors are currently available but you will also find further information on the NANOSENSORS™ MSS 8 Channel Readout Module ( MSS-8RM ). The MSS-8RM is a basic electronic module to operate and to readout NANOSENSORS™ MSS that can be integrated in the researchers own set-up.
The Membrane-type Surface-stress Sensor (MSS) is a device to detect specific components in gaseous phase with high sensitivity using a piezoresistive nanomechanical sensor. This device shows great potential as a core component for artificial- (electric-) nose sensors/systems utilized in e.g., medical, food, environment, safety and security fields.
The working principle of the MSS is as follows: A receptor layer coated on the silicon membrane of a nanomechanical sensor yields surface stress upon absorption/adsorption of target molecules. Small beams supporting the membrane are then mechanically deformed and the integrated piezoresistors on the beams change their resistance. By monitoring the changes in resistance, one can detect the presence of the target molecules. The receptor material determines the sensitivity and the specificity of the device in detecting the target molecules.
The “SD-MSS-1K2GP” is basically identical to the “SD-MSS-1K2G”, which was introduced in 2017, except that the aluminum electrodes of the SD-MSS-1K2GP are covered with a silicon oxide layer.
The piezoresistors of the SD-MSS-1K2GP are covered with silicon nitride as the already introduced “SD-MSS-1K2G” model. Thus, the “SD-MSS-1K2GP” can be employed for “liquid” or “wet” applications. This feature extends the possibilites of usage for the MSS sensors, for example sensing of taste, detections of chemical reactions in solutions, etc.
Please note that the MSS Sensors platforms that NANOSENSORS offers are no plug-and-play devices. They are raw sensor platforms intended to support researchers in the fields of smell/odor sensing with a platform for their research so that they don’t have to start their setup from scratch. The MSS sensors will still need to be coated with detection layers by the individual researchers in order to become functional sensors.
