Primary recommendation: doi.org/10.1351/PAC-REC-10-12-04 . Pure and Applied Chemistry 84(2), 377–410 (2012). Verified publisher byline: Michel Vert, Yoshiharu Doi, Karl-Heinz Hellwich, Michael Hess, Philip Hodge, Przemyslaw Kubisa, Marguerite Rinaudo and François Schué. Official PDF: publications.iupac.org/pac/pdf/2012/pdf/8402x0377.pdf . Entries 30 (biomaterial) and 106 (biocompatibility in biomedical therapy). Entry 30 is reproduced in the primary IUPAC Gold Book goldbook.iupac.org/terms/view/13881 .

Additional precise locator: entry 70, erosion, printed p. 391, defines degradation beginning at the surface and progressing inward; its notes discuss reaction versus reagent diffusion and discourage the wording bulk erosion. The official Gold Book reproduces this definition at goldbook.iupac.org/terms/view/13906 . Both the indexed primary recommendation and Gold Book entry were verified; direct-reader access to the PDF/entry returned 403. A mass-loss curve alone does not establish the spatial mechanism.

Primary project description. It names Michel Vert as chairman and discusses polymer-based therapeutic aids needed for limited periods, including resorbable fixation, sutures and delivery systems. Used for the project motivation and leadership rather than for clinical performance claims.
