Unlike most previous work, the particle need not be small in mass or dimension relative to the beam, and the adsorbate\u2019s geometric characteristics are incorporated into the model via its rotational inertia and eccentricity relative to the beam axis. For the special case in which the adsorbate\u2019s (translational) mass is indeed small, an analytical solution is obtained for the particle-induced resonant frequency shift of an arbitrary flexural mode, including the effects of rotational inertia and eccentricity. This solution is shown to possess the exact first-order behavior in the normalized particle mass and represents a generalization of analytical solutions derived by others in earlier studies. The results suggest the potential for \u201chigher-order\u201d nanobeam-based mass detection methods by which the multi-mode frequency response reflects not only the adsorbate\u2019s mass but also important geometric data related to its size, shape, or orientation (i.e., the mass distribution), thus resulting in more highly discriminatory techniques for discrete-mass sensing.<\/jats:p>","DOI":"10.3390\/s151129209","type":"journal-article","created":{"date-parts":[[2015,11,24]],"date-time":"2015-11-24T01:57:02Z","timestamp":1448330222000},"page":"29209-29232","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Toward Higher-Order Mass Detection: Influence of an Adsorbate\u2019s Rotational Inertia and Eccentricity on the Resonant Response of a Bernoulli-Euler Cantilever Beam"],"prefix":"10.3390","volume":"15","author":[{"given":"Stephen","family":"Heinrich","sequence":"first","affiliation":[{"name":"Department of Civil, Construction and Environmental Engineering, Marquette University, Milwaukee, WI 53233, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1986-1463","authenticated-orcid":false,"given":"Isabelle","family":"Dufour","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Bordeaux, Laboratoire de l\u2019Int\u00e9gration du Mat\u00e9riau au Syst\u00e8me, UMR5218 Pessac 33607, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,11,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Brand, O., Dufour, I., Heinrich, S.M., and Josse, F.
