The application of vegetable oil-based softeners canola oil and cottonseed oil in Solution polymerized styrene-butadiene rubber (SSBR) system composites was investigated. The results showed that when the aromatic oil was replaced by 5 parts of vegetable oil-based softeners in equal amounts in the base formulation of SSBR system, the work-ing performance of the rubber was better, the tear strength and elongation at break were improved and the tensile strength was reduced; the vulcanization time of the rubber prepared with vegetable oil-based softeners was significantly reduced compared with that of aromatic oil; the glass transition temperature of the rubber was significantly reduced and the cold resistance and snow performance of the rubber were improved.

In this paper, we report a novel antibody conjugated gold nanostars (AuNSs) as surface-enhanced Raman spectroscopy (SERS) probes for distinguishing cancer cells (A549 cells, H1229 cells) from normal cells (ATII cells). In such a probe, bovine serum albumin (BSA) was served as the protective agent and stabilizing agent, 4-mercaptobenzoic acid (4-MBA) was used as the Raman reporter to generate SERS signals as well as the conjugation agent for attaching CD44 antibody (anti-CD44) molecules to AuNSs, where anti-CD44 could effectively target to CD44 protein overexpressed cells. All the results of the experiments con¯rmed that more SERS probes have been targeted to cancer cells (A549 cells and H1229 cells) than that of normal cells (ATII cells) under the same condition. The anti-CD44 SERS probes hold a potential application in distinguishing cancer cells from normal cells with high sensitivity and good biocompatibility.
