BioAge s.r.l.
During an experiment to detect an affinity reaction on biological material, a molecule of interest is attached to the quartz crystal of the measurement channel, this deposition can be achieved by direct binding or by capture through another protein, the result of this process is to make the quartz sensitive to the molecule to be detected.

openQCM
The sensor is a surface sensitive quartz crystal capable of measuring phenomena at molecular scale. It works in vacuum, air and liquid environments. The QCM sensor is based on the piezoelectric properties of the quartz crystal. The application of an alternating current causes the mechanical vibration of the quartz crystal in the MHz range. The QCM technique measures the variations in quartz frequency for measuring the mass variations on its surface.

400C Series -
CH Instruments, Inc.
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).

Elettra -
BioAge s.r.l.
Elettra has been designed to operate on its own, but it is also possible to connect it to a PC to control it and acquire, view and save data thanks to its extremely easy to use software that runs under MS-Windows™. The data acquisition process can be controlled extremely quickly thanks to the PLAY, PAUSE and STOP keys. Captured data can be saved in an Excel compatible format and graphs saved as bitmap images. By clicking on a button, the software is able to open the Excel program installed on the PC, enter all the data and create countless graphs, ready to be inserted in your documents and publications. At any moment it is possible to take a picture of the graph showing the frequency variation and save it as a bitmap image, to be able to insert it in documents and publications. The same keys that are present on the instrument are found on the software, these allow you to control the instrument remotely. On the frequency variation graph it is possible to zoom in on the regions of interest, it is also possible to display two cursors on the graph, thanks to these cursors it is possible to easily and immediately calculate the value of the frequency variation between any two points on the graph. The software is extremely easy to use and performs many other useful functions, such as automatic recognition of the computer port to which the instrument is connected. BioAge builds tools and writes software only after having carefully listened to the needs and requirements of the users of the final products, this process has the purpose of creating products that are easily usable and that have all the characteristics and functions that the user expects to have.

EUREKA -
BioAge s.r.l.
Eureka is a QCM / EQCM (Quartz Crystal Microbalance) nanogravimetric measuring instrument capable of mass measurements in the order of nano-grams and pico-grams. Eureka can be used with gas and liquids, the cells are made by BioAge and sold with the instrument. The tool is the most versatile among those existing on the market, with an excellent quality / price ratio. It is a portable instrument as it is powered only by the PC USB port. The instrument is extremely compact, light, reliable and designed according to the current state of microelectronics. To use Eureka simply connect it to a PC USB port and install the capture software, running in Windows ™ environment,which turns out to be very simple to use, so you can do the first experiments in a very short time. For liquid measurements Eureka is an electrochemical system, therefore, electrochemical and nanogravimetric measurements can be performed at the same time (EQCM). Eureka, if connected to a self-powered portable PC, allows to perform measurements and experiments in total freedom in environments where grid voltage is not available,or experiments that are carried out in large areas in total freedom of movement. Measurements can be made on liquids, thanks to the static cell or the flow cell, or BioAge is able to design and create customized cells according to the needs of the user, varying volumes, dimensions and materials. The instrument is very versatile because the frequency measurement range can range from 0 to 50MHz, depending on the quartz crystal used. or use a gas cell designed for gas phase analysis, BioAge is able to design and produce customized cells according to the user's needs, varying volumes, dimensions and materials.The instrument is very versatile because the frequency measurement range can range from 0 to 50MHz, depending on the quartz crystal used. or use a gas cell designed for gas phase analysis, BioAge is able to design and produce customized cells according to the user's needs, varying volumes, dimensions and materials.
