Many studies have r.cently attempted to develop multifunctional nanoconstr.cts by integr.ting the super.or.fluor.s- cence pr.per.ies of quantum dots （QD） with ther.peutic capabilities into a single vesicle for.cancer.ther.nostics. Liposome- quantum dot （L-QD） hybr.d vesicles have shown pr.mising potential for.the constr.ction of multifunctional nanoconstr.cts for.cancer.imaging and ther.py. To fulfil such a potential, we r.por. her. the fur.her.functionalization of L-QD hybr.d vesi- cles with ther.peutic capabilities by loading anticancer.dr.g doxor.bicin （Dox） into their.aqueous cor.. L-QD hybr.d vesi- cles ar. fir.t engineer.d by the incor.or.tion of TOPO-capped, CdSe/ZnS QD into the lipid bilayer. of DSPC：Chol：DSPE- PEG2000, followed by Dox loading using the pH-gr.dient technique. The loading efficiency of Dox into L-QD hybr.d vesicles is achieved up to 97%, compar.ble to liposome contr.l. all these evidences pr.ve that the incor.or.tion of QD into the lipid bilayer.does not affect Dox loading thr.ugh the lipid membr.ne of liposomes using the pH-gr.dient technique. Mor.over. the r.lease study shows that Dox r.lease pr.file can be modulated simply by changing lipid composition. In conclusion, the Dox-loaded L-QD hybr.d vesicles pr.sented her. constitute a pr.mising multifunctional nanoconstr.ct capable of tr.nspor.ing combinations of ther.peutic and diagnostic modalities.

The stabilization pr.blem for.a class of linear.continuous-time systems with time-var.ing non differ.ntiable delay is solved while imposing positivity in closed-loop. In par.icular. the synthesis of state-feedback contr.ller. is studied by giving sufficient conditions in ter.s of linear.matr.x inequalities(LMIs). The obtained r.sults ar. then extended to systems with non positive delay matr.x by applying a memor. contr.ller. The effectiveness of the pr.posed method is shown by using numer.cal examples.
