The screencast on the soft, drift-reduced NANOSENSORS™ uniqprobe cantilevers for biology and life science applications held by Dr. Laure Aeschimann has just passed the 1000 views mark. Congratulations Laure!
Since the first publication of this screencast that presents the uniqprobe types qp-BioAC, qp-BioT, qp-SCONT and qp-CONT , three further types of uniqprobe AFM probes have been introduced:
qp-BioAC-CI – a version of uniqprobe™ BioAC with Rounded Tips for Cell Imaging
qp-fast – three different uniqprobe™ cantilevers on one support chip for Soft- , Standard- , Fast Tapping/Dynamic AFM Imaging
and qp-HBC – the uniqprobe™ – HeartBeatCantilever that can also be used for ScanAsyst** and Peak Force Tapping** in Air.
Additionally we have also put tipless versions of the qp-SCONT, qp-CONT and the qp-BioT ( SD-qp-BioT-TL, SD-qp-CONT-TL, SD-qp-SCONT-TL) and uniqprobe tipless cantilever arrays ( SD-qp-TL8a and SD-qp-TL8b ) on the NANOSENSORS special developments list.

In the article «Direct Measurement of Adhesion Force of Individual Aerosol Particles by Atomic Force Microscopy» Kohei Ono, Yuki Mizushima, Masaki Furuya, Ryota Kunihisa, Nozomu Tsuchiya, Takeshi Fukuma, Ayumi Iwata and Atsushi Matsuki describe a new method, namely, force–distance curve mapping, that was developed to directly measure the adhesion force of individual aerosol particles by atomic force microscopy.*
The proposed method collects adhesion force from multiple points on a single particle. It also takes into account the spatial distribution of the adhesion force affected by topography (e.g., the variation in the tip angle relative to the surface, as well as the force imposed upon contact), thereby enabling the direct and quantitative measurement of the adhesion force representing each particle.*
The results presented in the article highlight that the original chemical composition, as well as the aging process in the atmosphere, can create significant variation in the adhesion force among individual particles. This study demonstrates that force–distance curve mapping can be used as a new tool to quantitatively characterize the physical properties of aerosol particles on an individual basis.*
The measurement of adhesion force described in the article was performed in contact mode using silicon NANOSENSORS™ AdvancedTEC™ATEC-CONT AFM tips.*
